Ovarian Cancer Causes & Risks

Causes

The causes of ovarian cancer are not known. However, research shows that certain risk factors are associated with the disease.

Risk Factors

Factors that increase your chance for ovarian cancer include:

  • Family history of ovarian cancer, especially in mother, sister, or daughter
  • Age: 50 or older
  • Menstrual history—first period before age 12, no childbirth or first childbirth after age 30, and late menopause
  • Personal history of breast cancer or colon cancer
  • Certain gene mutations, including BRCA1, BRCA2

Use of birth control pills for more than five years appears to decrease risk.
