Radiation therapy for stomach cancer

Radiation therapy for stomach cancer (also known as radiotherapy) uses x-rays to damage or kill cancer cells so they cannot multiply. The radiation is targeted at the parts of the body with cancer. Treatment is carefully planned to do as little harm as possible to healthy body tissue.

Radiation therapy for stomach cancer is usually used to control symptoms when surgery is not suitable. In this case, you will have a simple, short course (1–2 weeks) of external beam radiation therapy. This is unlikely to cause any side effects, apart from some possible nausea. Each treatment takes about 15 minutes and is not painful. You will lie on a table under a machine that delivers radiation to the affected parts of your body. Your doctor will advise you about your treatment schedule.
