Infographic: Breast Cancer and Genetics


Breast cancer is the most common cancer among American women, but only 5-10 percent of breast cancer cases are hereditary. Of those cases, roughly 20-25 percent are linked to mutations in the BRCA1 and BRCA2 genes (BRCA stands for BReast CAncer susceptibility).

View the infographic below for more on the genetics of breast cancer.
