Cancer is a disease in which cells in the body grow out of control. Cancer is always named for the part of the body where it starts, even if it spreads to other body parts later. When cancer starts in the ovaries, it is called ovarian cancer. Women have two ovaries that are located in the pelvis, one on each side of the uterus. The ovaries make female hormones and produce eggs.
Ovarian cancer causes more deaths than any other cancer of the female reproductive system. But when ovarian cancer is found in its early stages, treatment is most effective. Ovarian cancer often causes signs and symptoms, so it is important to pay attention to your body and know what is normal for you. Symptoms may be caused by something other than cancer, but the only way to know is to see your doctor, nurse, or other health care professional.
Who Gets Ovarian Cancer?
All women are at risk for ovarian cancer, but older women are more likely to get the disease than younger women. About 90% of women who get ovarian cancer are older than 40 years of age, with the greatest number of cases occurring in women aged 60 years or older.
Each year, about 20,000 women in the United States get ovarian cancer. Among women in the United States, ovarian cancer is the eighth most common cancer and the fifth leading cause of cancer death, after lung and bronchus, breast, colorectal, and pancreatic cancers. Ovarian cancer causes more deaths than any other cancer of the female reproductive system, but it accounts for only about 3% of all cancers in women. When ovarian cancer is found in its early stages, treatment is most effective.†
