For women who have one relative with ovarian cancer
If a woman in your family—such as a mother, a sister, or a daughter—has had ovarian cancer, your risk of getting it is a littler higher than women who don’t have a family history of the disease. About 5 out of 100 women with a family relative who has had ovarian cancer will get this cancer.

For women who have two or three relatives with ovarian cancer
If 2 or more relatives in your family have had ovarian cancer, your risk for getting it goes up. About 7 out of 100 women with 2 or more family relatives who have had ovarian cancer will get this cancer.

For women who have BRCA1 gene changes
Of the small number of women who get ovarian cancer, only a few will have inherited gene changes called BRCA1. The lifetime risk for getting ovarian cancer for these women is much higher than average. For these women, about 40 out of 100 women will get ovarian cancer.
