Radiation therapy uses high-energy X-rays to kill cancer cells. It can be given along with other treatments, including chemotherapy.
The radiation comes from a large machine. The machine aims beams of radiation at the cancer in the abdomen. You’ll go to a hospital or clinic 5 days a week for several weeks to receive radiation therapy. Each session takes about 30 minutes.
Although radiation therapy is painless, it may cause other side effects. The side effects include nausea, vomiting, or diarrhea. You may also feel very tired. Your health care team can suggest ways to treat or control these side effects.
