Radiotherapy for ovarian cancer

Radiotherapy treats cancer by using high-energy rays to destroy the cancer cells, while doing as little harm as possible to normal cells.

Radiotherapy is rarely used to treat ovarian cancer. It is occasionally used to treat an area of cancer that’s come back after surgery and chemotherapy when other treatments are no longer appropriate.

It may also be used to reduce bleeding, pain or discomfort. This is known as palliative radiotherapy.

Radiotherapy is given in the hospital radiotherapy department. A course of palliative treatment may be given over 1–10 sessions. Each session lasts a few minutes. The length of your treatment will depend on the type and size of the cancer. Your doctor will discuss your treatment with you in detail beforehand.

We have more information about how radiotherapy works and the different types.
