Making Strides Against Breast Cancer is the American Cancer Society's premier event to raise awareness and funds to fight breast cancer. It’s more than just the name of a walk – it describes the amazing progress we’re making together. A world with less breast cancer is a world with more birthdays. That world gets closer and closer at every American Cancer Society Making Strides Against Breast Cancer walk. Since 1993, 6 million Making Strides walkers have raised more than $400 million.
