Ovarian cancer is “staged” through a surgical process that examines tissues to see if there is evidence of cancer and if cancer may have spread. The process of staging determines whether the cancer has spread beyond the ovaries, and what organs are involved. Treatment is based on the stage of the cancer, but generally involves surgical removal of as much of the cancer as possible, followed by chemotherapy. When the cancer is limited to one or both ovaries, but has not spread, the five year survival rate may be as high as 90%. New treatments are being studied with the hope that there will be more options for women with ovarian cancer.
