What option exists to decrease the risk of breast cancer in women with BRCA mutations?

• A. Annual MRI screenings
• B. Prophylactic bilateral mastectomy
• C. Tamoxifen therapy
• D. Regular mammogram checks

Answer: (B)

The option to decrease the risk of breast cancer in women with BRCA mutations is prophylactic bilateral mastectomy. This surgical procedure involves the removal of both breasts, significantly reducing the likelihood of breast cancer developing in individuals who carry BRCA1 or BRCA2 mutations, as these mutations increase the risk of breast and ovarian cancers considerably. By choosing this proactive measure, women can effectively lower their cancer risk from approximately 85% to less than 5%, thereby providing a strong preventative strategy for those with a genetic predisposition to breast cancer.

While annual MRI screenings, Tamoxifen therapy, and regular mammogram checks can be part of the management and monitoring of breast health, they do not offer the same level of risk reduction as prophylactic mastectomy. MRI screenings are useful for early detection in high-risk individuals, but they do not prevent cancer. Similarly, Tamoxifen is a medication that can lower the risk of hormone receptor-positive breast cancer but is not as effective as surgical intervention for those with BRCA mutations. Regular mammograms are a standard practice for breast cancer screening but are also not preventative, as they primarily focus on early detection rather than risk elimination.
