Breast cancer is a complex disease with no simple solution. Research is the key to stopping it in its tracks. Founded in 1993 by Evelyn H. Lauder, the Breast Cancer Research Foundation is the largest private funder of breast cancer research in the world. We invest in the best minds in science—and foster cross-disciplinary collaboration—to examine every aspect of the disease from prevention to metastasis. Our approach accelerates the entire field and moves us closer to the answers we urgently need.
