    slide 2 of 5, For women who have one relative with breast cancer,

    If one woman in your family-such as a mother, a sister, or a daughter-has had breast cancer, your risk of getting it is a little higher than for women who don't have a family history of the disease. About 24 out of 100 women with one relative who has had breast cancer will get this cancer sometime during their lives.
