The NCCN recommends risk-reducing salpingo-oophorectomy (RRSO), typically between 35 and 40 years, and upon completion of childbearing in BRCA1 mutation, while it is reasonable to delay RRSO for management of ovarian cancer risk until age 40-45 years in patients with BRCA2. This evidence concerns the gene BRCA1 and ovarian cancer.
