Chemotherapy and Cancer Treatment, Coping with Side Effects
What Causes Side Effects?
Because cancer cells may grow and divide more rapidly than normal cells, many anticancer drugs are made to kill growing cells. But certain normal, healthy cells also multiply quickly, and chemotherapy can affect these cells, too. This damage to normal cells causes side effects. The fast-growing, normal cells most likely to be affected are blood cells forming in the bone marrow and cells in the digestive tract (mouth, stomach, intestines, esophagus), reproductive system (sexual organs), and hair follicles. Some anticancer drugs may affect cells of vital organs, such as the heart, kidney, bladder, lungs, and nervous system.
You may have none of these side effects or just a few. The kinds of side effects you have and how severe they are, depend on the type and dose of chemotherapy you get and how your body reacts. Before starting chemotherapy, your doctor will discuss the side effects that you are most likely to get with the drugs you will be receiving. Before starting the treatment, you will be asked to sign a consent form. You should be given all the facts about treatment including the drugs you will be given and their side effects before you sign the consent form.
How Long Do Side Effects Last?
Normal cells usually recover when chemotherapy is over, so most side effects gradually go away after treatment ends, and the healthy cells have a chance to grow normally. The time it takes to get over side effects depends on many things, including your overall health and the kind of chemotherapy you have been taking.
Most people have no serious long-term problems from chemotherapy. However, on some occasions, chemotherapy can cause permanent changes or damage to the heart, lungs, nerves, kidneys, reproductive or other organs. And certain types of chemotherapy may have delayed effects, such as a second cancer, that show up many years later. Ask your doctor about the chances of any serious, long-term effects that can result from the treatment you are receiving (but remember to balance your concerns with the immediate threat of your cancer).
The side effects of chemotherapy can be unpleasant, but they must be measured against the treatment's ability to destroy cancer. Medicines can help prevent some side effects such as nausea. Sometimes people receiving chemotherapy become discouraged about the length of time their treatment is taking or the side effects they are having. If that happens to you, talk to your doctor or nurse. They may be able to suggest ways to make side effects easier to deal with or reduce them.
