No matter who you are or where you live, breast cancer may touch your life. Breast cancer is the most common cancer among women in the U.S. and around the world. In 2018, about 266,120 women will be diagnosed in the U.S. alone.

Progress in treatment and early detection has led to improved survival for people of all ages and races, and with all stages of breast cancer. In fact, there are more than 3.5 million breast cancer survivors in the U.S. today (more than any other group of cancer survivors)!  However, there are more than 150,000 women and men living with incurable, metastatic breast cancer, and more than 41,000 women and men will lose their lives to the disease.  Our mission has never been more urgent.
