This is a genotype with recommended actions if clinically confirmed. In brief:

  • More frequent and more intensive screening for breast and ovarian cancer is recommended starting at perhaps age 25; however, screening has not been shown to reduce breast cancer incidence.
  • Prophylactic surgery (e.g. bilateral mastectomy or salpingo-oophorectomy) has been shown to substantially reduce the risk for, as well as mortality from, breast or ovarian cancer in both high-risk women and those who are BRCA mutation carriers.
  • Genetic counseling and/or testing is recommended for first-degree relatives as well as the same surveillance as carriers.
