Radiotherapy is the use of high energy x-rays, and other types of radiation, to treat cancer.
The organs and tissues of the body are made up of tiny building blocks called cells. Radiotherapy causes physical and chemical damage to the cancer cells in the treated area. Although normal cells are also affected, they can repair themselves and are able to recover.
Radiotherapy itself is painless and does not make you radioactive.
Radiotherapy can be applied safely to a wide range of cancers, and may be used alone or in conjunction with surgery, chemotherapy and other treatments. It is usually completely non-invasive, and accessed through out-patient clinics.
Treatment for each patient is planned individually, and even patients with the same type of cancer may not receive identical treatment.
It is advisable that you do not become pregnant during your treatment. If you suspect that you may be pregnant you must speak to a member of staff.
