Chemotherapy is the procedure to treat cancer cells by using chemicals. Cancer cells have the ability to divide rapidly. But in this procedure, both the good and bad cells are being killed although it is really aimed at killing the cancerous ones. There are a number of ways chemotherapy drugs are taken. It may be by mouth, by injection on the muscle or vein, by catheter inserted into our bladder, abdomen, chest cavity, spinal cord, liver and brain.

When oral chemotherapy is done, a patient is given a certain dosage to take. It may be daily, weekly or monthly. Most medications are advised to be taken on an empty stomach. There are times drinking juice is also recommended after taking in a medicine. The downside of an oral therapy is the possibility of a patient not to follow the prescribed dosage and time of medication. If done so, it may result to a less effective treatment or more severe consequences.

Intravenous chemotherapy is done through inserting a catheter. It may be inserted on any one of his body parts such as bladder, abdomen or chest. Every time a patient visits the clinic/hospital for treatment, the device where the medicine is placed is just inserted into the opening of the catheter. This enables the medicine to efficiently flow to the bloodstream of the body.

Injection chemotherapy is done usually after doing the intravenous chemotherapy. The patient undergoes a series of injection of medicines. Depending on the dosing cycle instructions, it is done a number of times in a day. The patient can do this procedure either at home or in a clinic.

Topical chemotherapy is done when a patient has skin cancer. The patient is advised to apply cream chemotherapy drugs on a cancerous area. Again, the frequency and dosage is determined by the oncologist. The patient is also advised not to be in direct contact with anybody/anything within the first hour of application. Some cream dries up faster but others take around an hour.

Doctors usually recommend full cycle chemotherapy. A full cycle is taken six times. But this is still dependent on the advice of the oncologist. Some of them may only recommend that some patients may only have three. Though this only happens when the patient's cancer cell isn't that fast-growing. The most common side effect of chemotherapy known to us is hair loss. There are other side effects of chemo. This includes nausea or vomiting, appetite loss, anemia, weakened immune system, easy bruising or bleeding, kidney and heart muscle damage, infertility and stop of menstrual cycle. The number of these after-effects is the reason why cancer patients sometimes want a partial chemo instead. Some of them think that the reaction of their body to the treatment is just unbearable.
