Chemotherapy and Reflexology

Reflexology is a zonal therapy and a science in which skillful manipulation is applied to the individually identified points on the body for stimulation of each functional system or parts of the body. These stimulation areas are basically located on the feet and the hands. It can help alleviating many problems in natural way. Reflexes are generated due to the manipulation of the response focal points on the body for each functional system for the resultant response. These response focal points have been effectively used in getting relief from a wide range of ailments with no chance of adverse side effects, otherwise, inevitable in case of chemotherapy. It has proved beneficial in rendering stress, pain, anxiety and nausea.

The first evidence of efficacy of the reflexology lies in innumerable corroborations by the patients endorsing easy relaxation followed by the quick and soothing feeling. Besides this, there are endorsements from the patients of great relief with positive results in treatment of cancer with no chances of any kind of side effect. There have been stories and claims that since reflexology eliminate toxins of the body, chemotherapy ceases to be effective.

It is reported that the patients at the large get the ability to cope up with chemotherapy and the related side effects. The oncology units of Charring Cross Hospital, Lister Hospital, Hammersmith Hospital and Harley Street Clinic are a few among many who have adopted using reflexology as a complementary therapy. As an endorsement to the efficacy and god results, many Macmillan cancer relief hospices and day care centers have inducted the technique in their treatment routine.

The technique has one good seriously helping the patients of lymphoedma (swelling of limbs) patients, after surgical removal of lymph glands by improving the circulation and the flow of lymph. Certain cases of lymphodeoma are quite painful due to accumulation of the fluids. In such cases reflexology techniques have proved to be good supportive action to induce flow or lymphatic drainage. It has been also found improve circulation, cause relaxation and better breathing.
Apart from effects in cases of lymphatic problems, there have been reports where other health related issues were addressed by the reflexology. There are reports of tackling weight loss, improving circulations, prostrates problems, hyperthyroidism, and several minor diseases.

It is important that the patients must voice their problems openly, and accept or endorse good effects of a treatment freely, just not confining to there the experience only with close ones for a larger benefit.

Beating the Lack of Energy Due to Chemotherapy

A cancer patient undergoing chemotherapy suffers from side-effects like hair loss, vomiting tendency, loss of appetite and mouth sores. When they suffer this pain they take it as a package deal with the treatment and bear the pain throughout the treatment session. They feel that all the patients who undergo chemotherapy have to bear this traumatic condition which not only weakens the body but also affects the mental state of the person and snatches away the desire to live.

The patient feels lethargic and losses all energy. He feels tired and weak even if he does a light work; this is because chemotherapy treatment adversely affects the healthy red and white blood corpuscles and destroys them. The body takes its own time to repair the damage. During that period the patient feels as though his body has been drained of all energy and this makes him weak which also develops the lethargic feeling.

All the adverse effects of chemotherapy can be warded off by taking herbal drugs made by combining many herbs which have the potentiality to rejuvenate the healthy cells and bring them up to their normal level. It has two fold effects, the person is saved from the agony of the dangerous side-effects and the healthy white cells, that is the bodies armed force fights against the cancerous cells and helps in the process of eliminating them.

The natural herbs work efficiently as they are combined together which increases their potentiality. Nearly 15 natural herbs having the potential to fight cancer are combined to form the drug. The effect of the combination is more on the body which helps the body to recover rapidly and overcome the adverse effects of chemotherapy. If these herbs are taken individually they might not prove to be as effective as a single herb does not contain all the anti-oxidant properties.

These herbal drugs can be taken prior to the commencement of the chemotherapy and can be continued during the treatment and also after the completion of the chemotherapy treatment. The herbal drug can be taken without the fear of facing any side effect as it has been scientifically proved that herbs do not have any adverse effect on the body. A patient can take the advantage of both the medical and the herbal treatment and relieve his body from a terminating disease to lead a healthy life.

Lung Cancer - Symptoms You Should Look Out For!

The implications of lung cancer are fatal and hence its seriousness cannot be undermined. Though steps cannot always be taken to prevent the disease, its symptoms can be understood and the paranoia reduced. A basic awareness of lung cancer symptoms can help us combat the disease.

The following are the frequently reported symptoms of lung cancer:

* The shortness of breath, which is more commonly known as dyspnea, is a symptom. Though excessive physical activity warrants dyspnea, it is also a lung cancer symptom.
* The coughing up of blood, which is medically known as hemoptysis, is an indication. It should not be confused with hematemesis, which denotes blood vomiting.
* An ache while coughing could be a warning. When there is an uncommon change in the pattern of coughing, lung cancer should be suspected.
* Weight loss, extreme exhaustion and a lack of desire for food, also called cachexia, can also be considered a symptom.
* Chest pain, which again is associated with heart disease and other medial causes, is a sign of lung cancer.

The following are the less common symptoms of lung cancer:

* Hoarseness in voice, medically termed as cachexia, is an indication the disease.
* A complication in swallowing, also known as dysphagia, is yet another sign. Though painful swallowing could also be classified under odynophagia, dysphagia should not be ruled out.
* Swelling of the face and the neck could be a sign of lung cancer. Where swelling in the neck arises due to bloated lymph nodes, the main blood vessel blockage from the head is the reason for facial swelling.
* Deformity in fingers and fingernails, also known as finger clubbing could be an uncommon lung cancer symptom.
* Apart from dyspnea, the shortness of breath could also be caused by pleural effusion. Pleural effusion is uncommon and denotes fluid around the lungs.
* Cancer that spreads itself at the upper lung is called pancoast tumor. This tumor could lead to a shoulder pain, pain in the bones, muscle weakness, weakening eyelids and a decrease in the sweating on a side of the face.

There are certain lung cancer symptoms, which are considered odd. These odd symptoms occur due to the unwelcome hormones brought about by lung cancer. These are:

* Protrusion of the eyes
* Numbness in the fingers, hands or legs
* Manifestation of lumps in the skin
* Changing sugar levels and an excruciating pain in the abdomen
* Swelling of breasts in men
* Manifestation of a lump in the tonsil or a salivary gland

It is important to look out for the common, uncommon as well as the rare symptoms of lung cancer. The doctors should be notified immediately so that they perform a diagnosis and clarify the underlying cause. Establishment of the cause, whether lung cancer or not, could hasten the treatment and lead to the betterment of the patients.

The Miracle Cure - Does Red Rice Cure Cancer?

THE BACKGROUND

It has been widely reported in the press that a possible "miracle cure" for cancer has been discovered in Chinese food. Not only that, there are also claims that the chemical concerned can help cure heart disease.

THE FACTS TO DATE

The miracle component is an extract of red yeast rice and is that which gives dishes such as Peking Duck its distinctive red colour. Scientists have claimed that if their findings are correct, it could CUT CANCER DEATHS BY A STAGGERING TWO-THIRDS and HEART DISEASE BY A THIRD.

In terms of heart disease, scientists feel that the extract has the potential to play an important part in improving heart health as initial findings indicate that it's performance is better than statins, the traditional drugs prescribed routinely for the treatment of high cholesterol.

When given to patients who had already suffered from at least one heart attack, the chances of a repeat attack were reduced by an amazing 45%.

No individual results are available for the types of cancers which were treated in the study group. However, scientists claimed to be "confident" that the initial findings are significant.

A leading doctor, David Capuzzi gave the following warning though.

"It is important to recognize that we do not know exactly how Chinese red yeast rice works...the capsules used in the study were carefully prepared for the research and are not the same as the red yeast supplements available in health food stores"

He and other doctors have strongly warned against buying over the counter supplements to self-medicate saying that these would not have the same effect. In addition, doctors have confirmed that consuming huge quantities of red rice would not be beneficial. Indeed either of these two practices could be dangerous.

We can only await further findings with great interest. I, for one, will be keeping a very close eye on developments.

ALTERNATIVE CANCER TREATMENTS

Although I am very much an advocate of alternative therapies and treatments, personally I would never recommend omitting standard medical and surgical treatments for cancer. However, I do feel that alternative complementary therapies can work very well alongside traditional treatments and a book I have discovered recently exemplifies this perfectly.

The book is called THE ALTERNATIVE TREATMENT-OVER 350 CANCER TREATMENTS THAT WORK.

In addition, the price includes 3 further ebooks completely free of charge.

Here is the total package:

NATURAL CANCER TREATMENTS - The most comprehensive book of its kind anywhere in the world. Over 350 treatments and 400 fully-indexed pages with a comprehensive table of contents enabling you to quickly locate information.

Killing the Killer Cancer

The number of people who die from cancer each year is more than the addition of HIV/AIDS malaria and tuberculosis combined together.The human body inhibits various forms of grwoth.The benign forms do not have the ability to spread to distant organs is not referred to as cancer. A typical example is the fibroid or uterine fibroma. However the growth of cells that have acquired the property of multiplying and spreading by various means of blood vessels or lymphatic channels to other organs like the lungs or bones are named as malignant cancers. The other human induced causes of cancer include smoking which is associated with lung cancer, Radiation to sarcomas and leukemia and other various viruses. Cancer often implicates a genetic element in the body during its development.

The Oxford Medical dictionary says that in half of all the cancerous developments a gene named as P53 is deleted or impaired which prevents the uncontrolled division of cells in the body, thus disabling the bodies fight against spread of cancer. The p54 is a gene which in the event of mutilation would form a gene called ontogeny which is capable of both initiation and continuation of malignant transformation of normal cells. It probably produces proteins which are growth factors regulating cell division that, under certain conditions become uncontrolled and may transform a normal cell to a malignant cell. Recent trials of gene therapy that involved replacing the ontogeny with the normal version of the gene have had limited success.

A cancer treatment often depends on the type of the tumor, the location of primary tumor and the extent of its spread. Some experts cite the early detection of the disease is the only cure for this disease. Here the cure defiles itself as the state of inability of the abnormal cells to grow and spread in the body.Those remains in the body in a state of suspended animation until death. There have been occasions where an absolute cure can be achieved by the removal of the cancer from the body by surgery. Here the grade of the malignancy can be determined due to the act of defining the stage, type or degree of cellular division. If the cancer is in early stages then it is hoped that almost all of it has been cut or excised and adequate radio therapy to the area where the tumor is can further assure the patient of satisfactory results of the surgery.

Specialized drugs though toxic to the cells provide useful adjuvant chemotherapy to the patients. Due to the toxic nature their selection has to be careful so that the patient can avail of their full treatment to get cured. Since inappropriate dosages can end up being toxic to 'good cells' of the blood and the gastro-intestinal tract. Specialized counters have been made for the the supply and distribution of these drugs, not a ordinary pharmaceutical medicine you find at any medical store.

The best ways of curing cancer include early detection of it through surgery, radiotherapy and chemotherapy. They have been bringing a hope to all patients suffering from cancer. Cancer management is a tedious tasks often a multidisciplinary approach involving surgeons, physicians, medical and radiological oncologists, pathologists, nursing care as well as palliative doctors. Management of cancer from the earliest time of discovery must be regarded as a palliative procedure even if a cure is envisioned. Continuous counseling and maintenance of life style, including adequate dieting, is extremely important in the patients' continued well being. Support and motivation are always a vital part of any treatment. All these with a small magical thing called as hope can often help fight the worst cases of cancer on this planet. Take Lance Armstrong as an example. How did he do it?

A Meningioma Brain Tumor Diagnosis Needn't Be the End of the World!

Let's face it, on the list of scary things that can happen to someone, being diagnosed with a meningioma type brain tumor has got to be pretty high on anyones list. But, whether it's happened to you or to a loved one, a meningioma brain tumor diagnosis needn't be the end of the world.

In the summer of 2006 my wife was suffering from involuntary spasms in her leg. She initially thought this was probably a trapped nerve in her back, (Note to reader:- Unless you're a doctor, self diagnosis is a big no-no)!

When this started to happen on a fairly regular basis it became more than a little annoying and so a trip to the doctors was arranged. Thankfully we have a very good doctor who decided as a first option rather than a last one, to arrange an MRI scan. But an MRI scan on the head and not her back, where she had thought the problem may be!

The MRI scan was carried out and being rather optimistic by nature, we both thought that it would reveal nothing and that it would then be a case of physiotherapy or some such treatment. What happened next changed our lives overnight. A meningioma brain tumor was diagnosed as being the cause of the 'kicking leg' effect.

To say we were both shell shocked would be an understatement. When someone tells you you have a brain tumor, the automatic first thought is that you are going to die. Period. I know that was true for my wife and I'd be less than honest if I said that it wasn't the first thought in my head as well.

I believe it is the case that benign meningiomas are far more common in women than they are in men.

The fact is though, that a meningioma type brain tumor can be one of the most operable type of tumors there is. Also, they are most often benign, which was the case for my wife.

After the initial shock had subsided a little, we started to try to think positive again. We made an appointment with the neurosurgeon and my first question to him was, "how much pain will my wife experience?" His answer came as quite a surprise.

"No pain", he said. This man was exactly the sort of person you would want if someone was going to open up your skull and start delving around inside! He was the epitome of the word 'calm'. He exuded such a relaxed attitude to the whole affair that he instilled a great deal of confidence in both of us. We both began to feel that perhaps a meningioma brain tumor diagnosis was not going to mean the end of the world after all.

And so it proved. The 5 hour operation was a completed success. The meningioma was removed in one piece and after a few days in intensive care my wife was moved to a general ward area of the hospital to complete her recovery.

I kept asking her if she was in any pain and always the answer was "no". In fact we now look back and laugh at the fact that the most pain she experienced during the entire hospital stay was indigestion from the hospital food!

Within 10 days my wife was back home and the day after that she was back working on her computer. I tried to stop her but she wanted to do it, saying she was bored and just wanted to get back to normal.

So although it's a very scary thing to be told, a meningioma brain tumor diagnosis need not be the end of the world.

Cancer Approach and Treatment

Cancer which is one of the top three causes of mortality (death) in developed countries . There are more than one hundred types of cancer which affects various tissues & organs, blood and lymphatics and skin. There is a sense of despair, anger, anxiety when someone is diagnosed with cancer because many people associate cancer with suffering, pain and ultimately death. Modern medicine has made great strides in the war against certain types of cancer like childhood leukemia, skin, prostate and colon cancer but not against others like lung, brain, pancreas and liver cancer.

The likelihood of cure increase with early diagnosis and treatment i.e before the cancer has grown to large enough size that press against and cause damage to neighboring tissues and organs. The other concern is that the cancer has already metastasize (spread) to neighboring and distant tissues and organs. General symptoms of cancer include persistent fatigue, unintentional weight loss, prolonged fever or infection, and changes to the skin ( jaundice, darkening of skin, abnormal hair growth, skin itchiness).

Cancer is a very difficult disease to treat because it is a disease that involve your cell genes that control cell multiplication. Survival rate (doctors call it remission) varies depending on type and stage of cancer. For example about 49 percent, or about half, of people diagnosed with early-stage lung cancer live for at least five years after diagnosis. The five-year survival rate for people diagnosed with lung cancer that has spread (metastasized) to other areas of the body is 3 percent. Of the survived cases about 90% is due to surgery and balance by chemotherapy or radiotherapy. There are pros and cons using chemotherapy or radiotherapy is readily available on the internet . Both of these treatment as they can cause side effects or worse still cause secondary cancer.

The human body can defend itself against bacteria and viruses and even kill cancer cells through intervention of our immune system. Chemotherapy kills cancer cells as well as other useful cells including immune system cells (white blood cells) which are needed to defend our body against diseases and cancer. When someone has cancer he/she needs to strengthen his/her immune system to fight off the cancer. So chemotherapy cannot be considered as a good treatment for cancer and the same applies to radiotherapy. Furthermore doctors cannot detect cancer via X-Ray or MRI when it is smaller than 1 centimeter in size which is equivalent to 1,000 million cancer cells. So if a person has say 10 million cancer cells remaining in his/her body after chemotherapy or radiotherapy, doctors will say that the cancer is in remission as it can't be detected. But don't be surprised when a cancer patient suffer a relapse even after a remission.

To understand how to treat cancer we need to know why normal cells that make up tissues and organs become cancerous. Normal cells when continuously exposed for years to toxic environment become cancerous in order to survive. Reason being cancer cells have higher survival rate compared to normal cells as cancer cells thrives in anaerobic (lack of oxygen) environment, can generate its own blood vessels to supply nutrients, able to multiply more rapidly, can disguise itself from immune system cells, can dissolve normal cell walls and invade them, and can produce chemicals to destroy white blood (immune system)cells. In fact cancer cells can survive indefinitely in laboratory while normal cells can multiply about 53 times before it stop and cell death occurs. So the secret to treat cancer is to reverse the toxic environment that finally trigger normal cells to become cancerous. Cleansing of the the cell internal toxic environment and improving blood circulation is the key to reverse cancer.

The Many Feelings of a Diagnosis of Cancer

If you have been recently been given a diagnosis of cancer you are probably experiencing a wide variety of emotions: fear, anger, sadness, guilt, helplessness and anxiety. It is important to deal with these feelings so that they do not hinder you in your fight against the cancer. At some time or another almost all people with cancer will have some or all of the following feelings:

Denial and Disbelief

Newly diagnosed patients sometimes deny that they have cancer. After all, they think, I've not been that sick, how could I have cancer? Denial can be an obstacle to appropriate and timely treatment; you must accept the diagnosis to begin fighting the cancer.

Fear

The word cancer stirs up fears in everyone. Fears such as What is going to happen to me? Am I going to survive? Who is going to pay for all this medical care if I am sick? are very common in newly diagnosed cancer patients. Talking with others with cancer can help resolve some of the fears.

Anger

Anger may stem from feelings of Why did this happen to me? Anger also comes from the disruption of your life, goals and your dreams. Discussing your feelings with others who are in the same situation can help put these feelings into perspective.

Stress and Anxiety

Stress and anxiety are common reactions to a cancer diagnosis and may manifest with physical symptoms such as headaches, difficulty sleeping, and loss of appetite. The immune system may be affected so finding a means to relieve stress is very important. Go get a manicure or a massage, walk, read a good book. Attend a support group; ask your oncologist for a referral to a mental health professional for a consultation if you are not able to cope.

Loss of Control

A cancer diagnosis can make life seem out of control. You can help reduce these feelings of powerlessness by exercising the control you do have over your situation. Increase your knowledge and understanding of the cancer that you are diagnosed with, research your treatment options and the side effects of these treatments.

Guilt

You may blame yourself for causing your family worry and grief. You may worry about becoming a burden to your family; physically and financially. Support groups and counseling for both the patient and the family, can be helpful in the ability to overcome the destructive impact these feelings can bring.

Loneliness

It is not uncommon for newly diagnosed cancer patients to want to shut out everyone and everything at times but the support from caring friends and family can be a tremendous resource. They may not know how you feel, but they do want to help you.

Depression

Many patients with cancer and their families can experience some level of depression. Feelings of dread, hopelessness and a sense that life has no meaning are not uncommon feelings. If you experience symptoms of depression, ask your doctor for a referral to a mental health professional.

It is important to remember that you are not alone in your fight against cancer and to not lose hope. Researchers are constantly making discoveries that one day might result in a cure for cancer. In the meantime, the best hope for successful treatment comes from learning all you can about the details of the cancer diagnosis and the treatment options available. First, find out the name of the cancer, its size and location, where it started and if it has spread. Find out if it's usually a slow growing cancer or an aggressive one. You need this information for get an accurate understanding of your options.

Liver Cancer - Incidence, Symptoms, Causation, Diagnosis, Treatment and Prognosis

Liver cancer also known as primary or metastatic hepatic carcinoma is a fairly rare form of cancer in the western world (1% of all cancers) but much more common in Africa and parts of Asia (10% to 50% of all cancers). It is much more prevalent in men and incidence increases with age. Liver cancer is rapidly fatal, usually within 6 months from gastrointestinal hemorrhage, hepatic failure or metastasis.

TYPES OF LIVE CANCER
Most primary liver tumors are known as hepatomas (hepatocellular carcinoma and primary lower cell carcinoma). Some primary liver cancers originate in the bile duct and these are known as cholangiomas. Some rare liver cancers include Kupffer cell sarcoma and hepatoblastomas (which occur almost exclusively in children and are usually respectable and curable). Metastatic liver cancer is 20 times more common than primary liver cancer and after cirrhosis this is the leading form of liver related death.

SIGNS AND SYMPTOMS
Liver cancer does not normally cause symptoms until it is in an advanced stage.
Clinical effects of advanced liver cancers include:

1. A mass in the right upper side.
2. Tender, nodular liver on palpation
3. Severe pain in the epigastrium or upper right side
4. Weight loss, anorexia, weakness, fever
5. Occasional jaundice or ascites (fluid in the abdomen)

CAUSATION
The exact cause of liver cancer is unknown in adults but in children it may be a genetic disease. Adult liver carcinomas may result from environmental exposure to carcinogens such as mold, contrast media (no longer in use), androgens and oral estrogens, the hepatitis B virus or by damage to the liver due to cirrhosis caused by too much prolonged imbibing of alcohol.

DIAGNOSIS
Liver cancer is difficult to diagnose in the presence of cirrhosis, but several tests can help identify it: The combination of an imaging study (ultrasound, CT, or MRI scans) and an elevated blood level of alpha-fetoprotein will most effectively diagnose liver cancer, electrolyte studies may indicate increased sodium retention, a liver biopsy can make a definitive diagnosis.

TREATMENT
Treatments for primary liver cancer depend on the extent (stage) of the disease, age, overall health, feelings and personal preferences. Surgery is the most effective treatment for primary liver cancer, but this is not always possible due to the size or position of the tumor. Radiofrequency ablation is an option for people with small, unresectable hepatocellular tumors and for some types of metastatic liver cancers. During this procedure, the hepatic artery (the artery from which liver cancers derive their blood supply) is blocked, and chemotherapy drugs are injected between the blockage and the liver. Cryoablation may be an option for people with inoperable primary and metastatic liver cancers. Removing the whole liver and replacing it with a liver from another person is another possible form of treatment for primary liver cancer.

Even when treatments fail to provide much improvement in the liver cancer itself, pain and other signs and symptoms caused by liver cancer can be aggressively treated to improve quality of life. In general, the treatments available for children are the same as for adults, and the best approach depends on the stage and type of cancer as well as the child's age and overall health.

What You Need to Know About Brain Cancer

Malignant brain tumors occur in about 4.5 people per 100,000 population, they may occur at any age but brain cancer is the leading cause of cancer-related death in patients younger than age 35. In adults, incidence is generally highest between ages 40 to 60.

There are two main types of brain cancer. Primary cancers start in the brain. Metastatic cancers start somewhere else in the body and moves to the brain. The most common tumor types in adults are gliomas and meningiomas. In children, incidence is generally highest before age 1 and again between ages 2 and 12. The most common types of brain tumour in children are astrocytomas, medulloblastomas, ependymomas and brain stem gliomas.

CAUSES
What causes brain cancer is not exactly known but there has recently been a great deal of speculation on the role of cell phone radiation in the development of cancer. In fact, while studies generally have shown no link between cell phones and brain cancer, there is some conflicting scientific evidence that may be worth additional study, according to the FDA.

More accepted risk factors for brain cancer include; exposure to vinyl chloride and individuals with risk factors such as having a job in an oil refinery, as a chemist, embalmer, or rubber industry worker show higher rates of brain cancer. Other risk factors such as smoking, radiation exposure, and viral infection (HIV) have been suggested but not proven to cause tumors. Patients with a history of melanoma, lung, breast, colon, or kidney cancer are at risk for secondary brain cancer.

SIGNS AND SYMPTOMS
Onset of symptoms is usually insidious and brain tumors are often misdiagnosed. Brain Cancers cause central nervous system changes by invading and destroying tissues and by secondary effects such as pressure on the brain. Symptoms vary but in general, symptoms include: Abnormal pulse and breathing rates, deep, dull headaches that recur often and persist without relief for long periods of time, difficulty walking or speaking, dizziness, eyesight problems including double vision, seizures, vomiting and at the late stages of the disorder dramatic changes in blood pressure may occur. Although headaches are often a symptom of brain cancer, it is important to remember that most headaches are due to less serious conditions such as migraine or tension, not cancer.

DIAGNOSIS
In most cases a definitive diagnosis is made by a tissue biopsy. Other diagnostic tools include; patient history, a neurologic assessment, skull x-rays, a brain scan, CT scan, MRI, a lumbar puncture and cerebral angiography. Meningiomas, arising from the covering around the brain or spinal cord, account for about 20% of brain cancers and are generally more benign.

TREATMENT
How to treat brain tumors depends on the age of the patient, the stage of the disease, the type and location of the tumor, and whether the cancer is a primary tumor or metastases. Brain cancer are somewhat unique because of the blood brain barrier, which severely restricts the types of substances in the bloodstream that are allowed by the body into the brain and makes drug treatment extremely difficult. Because of this more and more research is being undertaken in delivering medication by means of nanoparticles, amongst the properties of nanoparticles that make them ideal candidates for recognizing and treating tumors, their ability to deliver a wide variety of payloads across the blood-brain barrier is perhaps the most important.

Brain cancer's location and ability to spread quickly makes treatment with surgery or radiation like fighting an enemy hiding out among minefields and caves, and explains why the term brain cancer is all too often associated with the word inoperable.

Brain cancer survival statistics for the deadliest of tumors such as gliomas have not improved significantly over the past two decades and the clinical armamentarium is, to a large extent, still dependent on surgery and radiation therapy, treatments known to leave survivors with devastating cognitive deficits. Gamma knife surgery is a radiosurgery technique used to treat people with brain cancer and other neurological disorders

The most deadly form of brain cancer may be treatable with a vaccine that uses proteins. Unlike measles or mumps vaccines, which are meant to prevent disease, the vaccine turns on the patient's own immune system so it will help kill the tumor. When the vaccine is injected, it stimulates the immune system to kill off brain cancer cells and prevent the regrowth of tumors that have already been treated.

PROGNOSIS
The chances of surviving for a person with a brain tumor: Prognosis greatly depends on all of the following: type of tumor extent of the disease size and location of the tumor presence or absence of metastasis the tumor's response to therapy, age, overall health, and medical history, tolerance of specific medications, procedures, or therapies. Metastatic brain cancer indicates advanced disease and has a poor prognosis. Unfortunately, the most common form of primary brain cancer, glioblastoma, is also the most aggressive and lethal but teratomas and other germ cell tumors although they have the capacity to grow very large may have a more favorable prognosis.

What is Cancer - Incidence, Diagnosis, Causation, Symptoms, Treatment and Prognosis

Cancer is second only to cardiovascular disease as the leading cause of death in the Western world. Although Cancer is primarily a disease of the elderly with more than 60% of deaths from cancer occurring in those over the age of 65, cancer can strike even the youngest of children.

Cancer appears to occur when the growth of cells in the body is out of control and cells divide too rapidly. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue.

Most common sites are:

Prostrate 24%
Breast 13%
Lung 13%
Colon and Rectum 9%
Bladder 3%
Uterus 2.5%

The cause of Cancer is believed to be a combination of genetic factors and outside carcinogens such as tobacco, viruses, infection, asbestos, vinyl chloride, inappropriate diet.

Cancer often has no specific symptoms, so it is important that you limit your risk factors and undergo appropriate cancer screening. The signs and symptoms will depend on where the cancer is, the size of the cancer, and how much it affects the nearby organs or structures.

If a cancer spreads (metastasizes), then symptoms may appear in different parts of the body. As a cancer grows, it begins to push on nearby organs, blood vessels, and nerves. If the cancer is in a critical area, such as certain parts of the brain, even the smallest tumor can cause early symptoms.

But sometimes cancers start in places where it does not cause any symptoms until the cancer has grown quite large. Pancreatic cancers, for example, do not usually grow large enough to be felt from the outside of the body. By the time a pancreatic cancer causes these signs or symptoms, it has usually reached an advanced stage.

A cancer may also cause symptoms common to many other problems, such as; fever, fatigue and weight loss. This may be because the cancer uses up much of the body's energy or it may cause the release of substances which affect metabolism.

Some lung cancers make hormone-like substances that affect blood calcium levels, affecting nerves and muscles and causing weakness and dizziness.

It is important to know what some of the general (non-specific) signs and symptoms of cancer are, but remember that having any of these does not mean that you have cancer.

Most cancers can be treated and some cured, depending on the specific type, location, and stage. The earlier the cancer is found, the better the prognosis.

A good example of the importance of finding cancer early is melanoma skin cancer. Skin cancer can be easy to remove if it has not grown deep into the skin, and the 5-year survival rate (percentage of people living at least 5 years after diagnosis) at this stage is nearly 100%.

Screening for breast cancer with mammograms has been shown to reduce the average stage of diagnosis of breast cancer in a population. Colorectal cancer can be detected through fecal occult blood testing and colonoscopy, which reduces both colon cancer incidence and mortality, presumably through the detection and removal of pre-malignant polyps. Similarly, cervical cytology testing (using the Pap smear) leads to the identification and excision of precancerous lesions.

Testicular self-examination is recommended for men beginning at the age of 15 years to detect testicular cancer.

SIGNS and SYMPTOMS

Pain may be an early symptom with some cancers such as bone cancers or testicular cancer.

Long-term constipation, diarrhea, or a change in the size of the stool may be a sign of colon cancer.

Pain with urination, blood in the urine, or a change in bladder function (such as more frequent or less frequent urination) could be related to bladder or prostate cancer.

Skin cancers may bleed and look like sores that do not heal.

A long-lasting sore in the mouth could be an oral cancer and should be dealt with right away, especially in patients who smoke, chew tobacco, or frequently drink alcohol.

Sores on the penis or vagina may either be signs of infection or an early cancer, and should not be overlooked.

Unusual bleeding can happen in either early or advanced cancer.

Blood in the sputum (phlegm) may be a sign of lung cancer.

Blood in the stool (or a dark or black stool) could be a sign of colon or rectal cancer.

Blood in the urine may be a sign of bladder or kidney cancer.

A bloody discharge from the nipple may be a sign of breast cancer.

Many cancers can be felt through the skin, mostly in the breast, testicle, lymph nodes (glands), and the soft tissues of the body. A lump or thickening may be an early or late sign of cancer.

While they commonly have other causes, indigestion or swallowing problems may be a sign of cancer of the esophagus, stomach, or pharynx (throat).

A cough that does not go away may be a sign of lung cancer.

A cancer may be suspected for a variety of reasons, but the definitive diagnosis of most malignancies must be confirmed by histological examination of the cancerous cells by a pathologist.

TREATMENT

Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy.

Radiation therapy may be used to treat almost every type of solid tumor, including cancers of the brain, breast, cervix, larynx, lung, pancreas, prostate, skin, stomach, uterus, or soft tissue sarcomas.

Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.

Contemporary methods for generating an immune response against tumours include intravesical BCG immunotherapy for superficial bladder cancer, and use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma patients.

Pain medication, such as morphine and oxycodone, and anti-emetics, drugs to suppress nausea and vomiting, are very commonly used in patients with cancer-related symptoms. transmission and disease.

Advances in cancer research have made a vaccine designed to prevent cancer available. The vaccine protects against four HPV types, which together cause 70% of cervical cancers and 90% of genital warts.

The consensus on diet and cancer is that obesity increases the risk of developing cancer. The cancer-fighting components of food are also proving to be more numerous and varied than previously understood, so patients are increasingly being advised to consume fresh, unprocessed fruits and vegetables for maximal health benefits.

What is Kidney Cancer?

There are basically three types of kidney cancer:

1. Renal Cell Carcinoma: Renal cell carcinoma is cancer that forms in the lining of very small tubes in the kidney that filter the blood and remove waste products.

2. Renal Pelvis Carcinoma: Renal pelvis carcinoma is cancer that forms in the center of the kidney where urine collects.

3. Wilms Tumor: Wilms tumor usually develops in children under the age of five.

This year, it is estimated that there will be 54,390 new cases diagnosed. It is also estimated that there will be 13,010 deaths caused by the disease.

People are born with two kidneys. One is located on each side of the spine in the lower abdomen. The good news is that people can live full lives with a normal life expectancy with only one. It is important to note here that all tumors found in the kidneys are not cancerous. As a matter of fact, most cancers found are benign.

Most often, renal cell carcinoma and renal pelvis carcinoma develop in people over the age of 40. There is no way to determine who is more likely to develop the disease but there are some factors that raise the risk.

Smoking: Smoking both cigarettes and/or cigars raises the risk of developing all kinds of cancer, including kidney cancer.

Obesity: Obesity seems to be a major risk factor in developing this type if cancer.

Gender: Men are more likely to get the disease than women. About 20,000 men and 12,000 women learn they have kidney cancer each year in the United States.

Occupation: Iron and steel workers and workers who are exposed to asbestos and cadmium are more likely to develop kidney cancer.

What is Pancreatic Cancer?

First, the good news - research is being done and scientists are learning more every day about the causes of pancreatic cancer. Progress IS being made, and research has already led to better treatment for the diasease, a better quality of life for patients, and a decrease in deaths from pancreatic cancer.

The pancreas is a little organ only about 6 inches long that is located between the stomach and the spine. It is responsible for producing insulin as well as other hormones. Additionally, it makes pancreatic juices containing enzymes that help in digesting food.

Most cases of cancer starts in the ducts that carry pancreatic juices. Cancer of the pancreas is also called carcinoma of the pancreas. The terms are used interchangeably.

*Note: There is a rare cases that start in the cells that make insulin and other hormones. Cancer that starts in these cells is called islet cell cancer.

There are, of course, certain risk factors that scientists say increase the chances of a person developing the disease. It is important to note, however, that many people with all of the risk factors do not get pancreatic cancer and that people who have none of the risk factors do get it.

The risk factors that scientists have identified are:

1. Smoking: Smoking increases the risk of developing all kinds of cancer, according to scientists.

2. Age: Most cases if this type of cancer are diagnosed in patients over the age of 60.

3. Race: African Americans have a greater risk of developing the diasease than other ethnic groups.

4. Sex: Males more often develop pancreatic cancer than females.

5. Family History: If there is a history of pancreatic cancer in the family, there is a greater risk for a patient to develop it.

Coping With Cancer Pain

Cancer can cause a great deal of pain. The treatments for cancer can also cause a great deal of pain. But pain is not a "done deal" - it isn't inevitable. Pain control is part of the overall treatment for cancer. Physicians have a whole arsenal of methods and options at their disposal. The best defense is always a good offense, whether you are talking about a football game, a basketball game, or fighting cancer pain.

First, there are a few facts that patients need to know: (1) pain CAN be managed; (2) talking openly with your physician will help him help you; (3) there are a great many pain medications, and when one doesn't work, another will; (4) people who take pain medications prescribed by their doctors for cancer-related pain very rarely become addicted to them; and (5) the human body does not become immune to pain medication. There is no point in "saving" a medication for later.

There are as many different causes of pain as there are patients who have pain. Pain relief does not come in a "one-size-fits-all" pill. It can be caused by medical tests, tumors, spinal cord compression, and treatments like chemotherapy and radiation therapy. There are different relievers available for pain that is caused by different things.

Doctors use prescription medications, of course, and all of the hundreds and thousands of pain medications can be prescribed for a cancer patient. But medications are not the only weapon to combat pain in the doctor's bag. Many doctors prescribe the use of such alternative medicines as aromatherapy, massage, acupuncture, biofeedback, and others.

The idea is often just to relieve the pain, but an even better idea is to prevent the pain in the first place. Talk to your doctor about pain prevention.
