All women are at risk for breast cancer.
The older you are, the greater your chance of getting it. Women who have a mother, sister or daughter with breast cancer are at a higher risk particularly if the relative's cancer occurred before menopause or in both breasts. In addition, any woman who has had breast cancer is also at greater risk for developing a second breast cancer. The majority of the women diagnosed with breast cancer have no known risk factors. Your chances of developing breast cancer depend on your individual history, not on your sexual orientation.
