A prophylactic mastectomy is a surgery to remove one or both breasts to reduce the risk of developing breast cancer. If you are at high risk of developing breast cancer (for example, there’s a strong family history), you might be exploring possible ways that you can reduce this risk. While a prophylactic mastectomy can significantly reduce risk of developing breast cancer, this surgery is also a serious decision that can have a considerable impact on your life. Take the time you need to talk to your surgeon and family members about the different ways you can lower your risk.
