In the fight against breast cancer, knowledge really is power. That’s why these women have made it their mission to teach others about the disease—making us all a little wiser and healthier. Each one of these women, whether they are breast cancer survivors themselves or have lost someone to cancer, want to educate women about early detection and to make sure women receive proper care. See what makes them so remarkable. Then lend a hand yourself. SHAPE, with the help of Lifetime, is asking you to sign a petition to help pass the bipartisan Breast Cancer Patient Protection Act. This would end the practice of so-called "drive-through" mastectomies when women are forced out of the hospital only hours after invasive breast cancer surgery. Sign the petition here.
