Information About BRCA

The majority of patients with hereditary breast and ovarian cancer have mutations in either the BRCA1 or BRCA2 genes. These mutations disrupt the body’s ability to repair DNA, which results in an increased susceptibility to cancer. In these families there are frequently several generations of women affected by breast and ovarian cancer, often at a young age. Other malignancies such as prostate, male breast, melanoma, and pancreatic cancers may also be observed.
