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 may occasionally be used to treat an area of cancer that’s come back after surgery and chemotherapy, if other treatment options are no longer appropriate.
It may also be used to reduce bleeding, pain or discomfort.
Radiotherapy is given in a radiation oncology unit. Your doctor (radiation oncologist) will discuss your treatment with you in detail beforehand.
