Radiation therapy for stomach cancer
Also known as radiotherapy, this treatment uses a controlled dose of radiation, such as focused x-ray beams, to kill or damage cancer cells.
Radiation therapy for stomach cancer is commonly used to control symptoms of pain, difficulty swallowing or bleeding. It is usually given as a short course (between one day and two weeks). Occasionally radiation will be given over a longer period (5–6 weeks), either before or after surgery, or if surgery is not possible.
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 let you know your treatment schedule. Possible side effects include fatigue, nausea, vomiting, diarrhoea and loss of appetite.
