mutation in the BRCA1 gene or the BRCA2 gene and by up to 90 percent in women who have a strong family history of breast cancer (2-5).
Bilateral prophylactic salpingo-oophorectomy has been shown to reduce the risk of ovarian cancer by approximately 90 percent and the risk of breast cancer by approximately 50 percent in women at very high risk of developing these diseases.
It inherently may be the better choice according to your family genes and history.
Women who inherit a deleterious mutation in the BRCA1 gene or the BRCA2 gene or mutations in certain other genes that greatly increase the risk of developing breast cancer may consider having bilateral prophylactic mastectomy and/or bilateral prophylactic salpingo-oophorectomy to reduce this risk.
In two studies, the estimated risks of developing breast cancer by age 70 years were 55 to 65 percent for women who carry a deleterious mutation in the BRCA1 gene
