The statistics can be overwhelming -- one in eight women will develop breast cancer during her lifetime. Knowing your odds, being informed and understanding how your genetics, your lifestyle choices and family history play a part in your risk of having cancer, can be one of your strongest weapons in confronting the disease. With current advancements in cancer research, physicians have a battery of tests to offer women that estimate individual risk of developing breast cancer. These models examine personal, medical, and familial history. Some evaluate the risk of a genetic mutation, like BRCA1 or BRCA2, while others look at exposure to endogenous hormones or benign breast disease.
