Identifying and managing hereditary risk of breast and ovarian cancer.
In the past, all women with a family history of breast or ovarian cancer were considered to be at increased risk of cancer themselves. The discovery of BRCA1 and BRCA2 demonstrated that susceptibility to breast and ovarian cancer can be inherited by women as a single-gene autosomal dominant disorder. For such women, evaluation of family history is an important screening tool to identify the possibility of hereditary cancer risk but only genetic testing can provide definitive, individualized risk assessment. Women who have inherited mutations in BRCA1 or BRCA2 now have several medical management options to address their increased risk of cancer. A well-educated community of health care providers and patients can use hereditary risk assessment, including genetic testing, to improve health care.
