Basic Information About 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. When cancer starts in either ovary, it is called ovarian cancer.
Fallopian tube cancer (which starts in the fallopian tube) and primary peritoneal cancer (which starts in the lining that supports the abdomen) are very similar to ovarian cancer. Many of the signs and symptoms are the same, and doctors treat these cancers in the same way. When ovarian cancer is found in its early stages, treatment works best.
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 in the United States, about 20,000 women get ovarian cancer and about 14,500 die from it. 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.
