摘要: Genetic predisposition is responsible for 5-10% of all breast cancer, and a much larger percent early-onset disease. Within the past few years, number genes associated with high risk cancer have been identified, including BRCA1, BRCA2, p53, Cowden disease gene PTEN/MMAC1. These appear to function as tumor suppressors, although their mutation frequency in general population low, certain populations carrier up 1% particular BRCA1 BRCA2 mutations. The isolation these likely provide important insight into pathogenesis human cancer. clinical application molecular discoveries raises controversial issues regarding presymptomatic testing patients suspected harboring predisposing
