Radiotherapy is the use of precise doses of high energy x-rays and other types of radiation to treat cancer. The radiation does not stay in your body and it is safe for you to mix with children and adults.

It is a painless treatment, similar to having an x-ray taken. It should take between 20 minutes and one hour to deliver. Radiotherapy is not routinely given on Saturdays and Sundays.

Radiotherapy can cure some cancers and also reduce the chance of a cancer coming back after surgery. It may be used to control a cancer or help improve the symptoms of it.

You may feel anxious about radiotherapy and this is perfectly normal. It can help to talk through any worries you have with your doctor, nurse or radiographer.
