Individual Champion/Changemaker | Division of Cancer Prevention
Long before scientists completed mapping the human genome in 2003, geneticist Mary-Claire King discovered BRCA1, the first gene for a hereditary form of breast cancer. That feat in 1990 helped explain why some women who carried mutations in this gene saw their lifetime risk for developing breast cancer rise from 8% to over 80%.
