Radiation
Radiation (also called radiotherapy, x-ray therapy, or irradiation) can be used alone or in combination with other treatments, such as chemotherapy, surgery, or biological therapy. It is a conventional medical therapy that can help:
- Kill cancer cells
- Shrink tumors
- Stop cancer cells from growing and dividing
Healthy cells are affected during radiation, but most appear to recover after treatments. Doctors will control the intensity of the radiation and the area affected to keep the side effects to a minimum.
How it's used: Radiation is administered at a hospital or treatment center in internal or external forms. Internal radiation requires a radioactive substance sealed in a container to be implanted into a tumor or body cavity. Sometimes an unsealed source is used and is taken orally or by injection. External radiation requires a machine that will direct high-energy rays at the tumor and surrounding area.
Side effects: Radiation side effects vary from person to person. The most common are: fatigue, skin changes, and a decrease in appetite. Visit the Coping with Side Effects Tool for strategies to help you to deal with these side effects.
