The term chemotherapy is used to describe cancer-killing drugs. Chemotherapy may be used to:
Cancer chemotherapy; Cancer drug therapy; Cytotoxic chemotherapy
HOW CHEMOTHERAPY IS GIVEN
Depending on the type of cancer and where it is found, chemotherapy drugs may be given different ways, including:
When chemotherapy is given over a longer period, a thin catheter can be placed into a large vein near the heart. This is called a central line. The catheter is placed during a minor surgery.
There are many types of catheters, including:
A central line can stay in the body over a long period of time. It will need to be flushed on a weekly to monthly basis to prevent blood clots from forming inside the central line.
Different chemotherapy drugs may be given at the same time or after each other. Radiation therapy may be received before, after, or during chemotherapy.
Chemotherapy is most often given in cycles. These cycles may last 1 day, several days, or a few weeks or more. There will usually be a rest period when no chemotherapy is given between each cycle. A rest period may last for days, weeks, or months. This allows the body and blood counts to recover before the next dose.
Often, chemotherapy is given at a special clinic or at the hospital. Some people are able to receive chemotherapy in their home. If home chemotherapy is given, home health nurses will help with the medicine and IVs. The person getting the chemotherapy and their family members will receive special training.
DIFFERENT TYPES OF CHEMOTHERAPY

SIDE EFFECTS OF CHEMOTHERAPY
Because these medicines travel through the blood to the entire body, chemotherapy is described as a bodywide treatment.
As a result, chemotherapy may damage or kill some normal cells. These include bone marrow cells, hair follicles, and cells in the lining of the mouth and the digestive tract.
When this damage occurs, there can be side effects. Some people who receive chemotherapy:
Side effects of chemotherapy depend on many things, including the type of cancer and which drugs are being used. Each person reacts differently to these drugs. Some newer chemotherapy drugs that better target cancer cells may cause fewer or different side effects.
Your health care provider will explain what you can do at home to prevent or treat side effects. These measures include:
