Even if other women in your family have had breast cancer, it does not automaticly mean the BRAC gene is present. Discuss it with your doctor. Dilligence in having your yearly check-ups and also knowing your own body are two of the best things you can do. In additon educate yourself on the signs of breast cancer. The educational material on this site is a great place to start.
Just because it runs in your family doesn't always mean you will get it, and also some women who don't have a family history do get it. (as in my case)
Just remember Knowledge is power.
