Information
HOW CHEMOTHERAPY IS GIVEN
Depending on the type of cancer and where it is found, chemotherapy drugs may be given different ways, including:
- Injections or shots into the muscles
- Injections or shots under the skin
- Into an artery
- Into a vein (intravenous, or IV)
- Pills taken by mouth
- Shots into the fluid around the spinal cord or brain
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:
- Central venous catheter
-

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.

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:
- Are more likely to have infections
- Become tired more easily
-
Bleed too much, even during everyday activities
