BRCA gene mutations account for about 5% to 10% of all breast cancers in females. About 72% of women having BRCA1 gene mutation and 69% of women having BRCA2 gene mutations are likely to develop breast cancer in their lifetime. In contrast, less than 12% of women in the general population are likely to develop breast cancer in their lifetime. Patients with germline BRCA2 gene mutation and diagnosed with localized PCa have reduced cancer-specific and metastasis-free survival than non-carriers.22 Those patients were having the affiliation of intra-ductal PCa and a germline BRCA2 mutation and undergoing surgery, and they have an inferior prognosis due to a reason of intraductal carcinoma.35,36 Recently, Taylor et al37 published an Jun 18, 2020 BRCA2 mutations are associated with an increased risk for: Breast cancer; Ovarian cancer; Melanoma; Pancreatic cancer; Prostate cancer.
