Susan G. Komen is the most widely known, largest and best-funded breast cancer organization in the United States. Since its inception in 1982, Komen has invested nearly $2 billion for breast cancer research, education, advocacy, health services and social support programs in the U.S. and through partnerships in more than 50 counties. Today, Komen has more than 100,000 volunteers working in a network of more than 120 affiliates worldwide. Susan Goodman, later Susan Goodman Komen, was born in 1943 in Peoria, Illinois. She was diagnosed with breast cancer at the age of 33. She dies of the disease at age 36 in 1980. Komen’s younger sister, Nancy Goodman Brinker, who believed that Susan’s outcome might have been better if patients knew more about cancer and its treatment, promised her sister that she would do everything she could to end breast cancer. To fulfill that promise, Brinker founded the Susan G. Komen Breast Cancer Foundation in Komen’s memory in 1982. Komen advocates for breast self-awareness as a primary method for fighting cancer. Komen supports universal screening mammography and breast self-examinations, as well as ever-increasing levels of government spending on diagnosing and treating breast cancer. They promote early detection as the primary tool for preventing breast cancer deaths.
