BRCA2 and ovarian cancer: We hypothesize that postponement of oophorectomy after salpingectomy, to the age of 40–45 (BRCA1) or 45–50 (BRCA2) years, compared with the current standard salpingo-oophorectomy at age 35–40 (BRCA1) or 40–45 (BRCA2) years, is non-inferior in regard to tubo-ovarian cancer risk.
