Radiotherapy may be offered as a complete treatment for some cancers, or before surgery to reduce the size of a tumour, or after surgery to make sure all the cancer cells are destroyed and to treat any cancer cells that may have spread around the site of the surgery, or as a palliative treatment if cancer is advanced. In this case it can treat symptoms, such as pain caused by cancer that has spread to the bones. Radiotherapy can also be given in conjunction with chemotherapy.

You may find it useful to have a look at the radiotherapy room of the Virtual Hospital Departments from The Royal College of Radiologists.

Most of the information in the sections listed below is about external beam radiotherapy. This is the most common type of radiotherapy treatment.
