Jan 31, 2025 · This surgery is often used to reduce the risk of ovarian and fallopian tube cancer in those who are at high risk for the disease because of inherited harmful changes in BRCA1, BRCA2, and several other genes.

Apr 15, 2024 · For women in whom gene testing finds “harmful changes” in the BRCA1 or BRCA2 genes, leading medical groups recommend that they take specific actions to lower their chances of being diagnosed with or dying from breast and ovarian cancer.

NCI-funded research helped identify inherited BRCA1 and BRCA2 genetic mutations and their connection to breast and ovarian cancer. From this research, a screening test was also developed to help patients make informed decisions about their health.
