Risk and Associated Factors
Age The rate of ovarian cancer increases with age and it is primarily a disease of older women.
Geneticsr The most important risk factor for ovarian cancer is a family history of a first-degree relative (mother, daughter, or sister) with the disease. The risk is higher still in women with two or more first-degree relatives with ovarian cancer.
Race & SES* Rates are slightly higher in Caucasian females than in African American females. The rate is higher among upper income groups.
Hormonal Risk of ovarian cancer is significantly reduced among women having at least one live-born child, a history of breast-feeding, or sustained oral contraceptive use. Highest risk is in post-menopausal women. It is also associated with a personal history of breast, endometrial, and colon cancers.
Diet Dietary fat may increase the risk.

There were no cases of ovarian cancer among persons aged less than 10 years. The age-specific incidence rates of ovarian cancer increased with age starting in the 20-24 age group. The highest age-specific rate was for women aged 80-84. No health district had significantly more cases than expected based upon rates for the remainder of Idaho.
