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.

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.

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.
