While many researchers have investigated the association between normal tissue biology and cancer development in the context of specific cancer types and the associated cancer drivers (e.g., the association between estrogen sensitive tissues, BRCA1/BRCA2 mutations and cancer development [9, 16, 17]), only a limited number of researchers have explored the genome-wide association between normal tissue and cancer gene activity across multiple cancer types. Here, BRCA2 is linked to cancer.
