Radiation therapy uses high-energy rays or particles to destroy cancer cells. Radiation is rarely used to treat ovarian cancer. It may be used:
The amount of radiation given during treatment, and when and how it is given, will be different for each person.
Ovarian cancer is usually treated with external beam radiation therapy. A machine directs radiation to the tumour and some of the surrounding tissue.
In systemic radiation therapy, a radioactive material (radioactive isotope) is taken by mouth or is injected into the body. It travels throughout the body and is absorbed by cancer cells. For ovarian cancer, a solution of radioactive phosphorus is instilled (gradually injected) into the abdomen. This treatment was used in the past, but is no longer part of the standard treatment for ovarian cancer.
