General Information About Ovarian Cancer
Key Points for This Section
Ovarian cancer is a disease in which malignant (cancer) cells form in the ovaries.
The ovaries are a pair of organs in the female reproductive system. They are in the pelvis, one on each side of the uterus (the hollow, pear-shaped organ where a fetus grows). Each ovary is about the size and shape of an almond. The ovaries make eggs and female hormones (chemicals that control the way certain cells or organs work in the body).
Ovarian cancer is the leading cause of death from cancer of the female reproductive system.
In recent years, there has been a small decrease in the number of new cases of ovarian cancer and the number of deaths from ovarian cancer. New cases of ovarian cancer and deaths from ovarian cancer are higher among white women than black women, but have decreased in both groups.
Women who have a family history of ovarian cancer and/or certain inherited gene changes, such as BRCA1 or BRCA2 gene changes, have a higher risk than women who do not have a family history or who have not inherited these gene changes. For women with inherited risk, genetic counseling and genetic testing can be used to find out more about how likely they are to develop ovarian cancer.
