Radiation therapy for ovarian cancer
Radiation therapy uses high-energy rays or particles to destroy cancer cells. Radiation is rarely used to treat ovarian cancer. It may be used:
- after surgery to destroy cancer cells left behind and to reduce the risk of the cancer recurring (adjuvantadjuvantTreatment given in addition to the first-line therapy (the first or standard treatment) to help reduce the risk of a disease (such as cancer) coming back (recurring). radiation therapy)
- occasionally when chemotherapy cannot be used
- For example, radiation therapy may be given to older women or those with another serious illness that prevents the use of chemotherapy.
- to relieve pain or to control the symptoms of advanced ovarian cancer (palliative radiation therapy)
The amount of radiation given during treatment, and when and how it is given, will be different for each person.
External beam radiation therapy
Ovarian cancer is usually treated with external beam radiation therapy. A machine directs radiation to the tumour and some of the surrounding tissue.
Systemic radiation therapy
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.
Seeing my sister Erin – a young mother – struggle with the emotional blow and then the physical toll of cancer treatment made me want to do something to help women feel confident.
Taking action against all cancers
The latest Canadian Cancer Statistics report found that of all newly diagnosed cancers in 2017, half are expected to be lung, colorectal, breast and prostate cancers. Learn what you can do to reduce the burden of cancer.
