In routine mammography exams, only 0.5% of the cases will have cancer present (Breast Cancer Surveillance Consortium, 2009), however if the patient has the BRCA1 or BRCA2 genetic mutation (colloquially referred to as the “breast cancer gene”), there is a 82% chance of developing cancer during their lifetime (King et al., 2003). This evidence concerns the gene BRCA2 and cancer.
