Key Concepts

BRCA Mutations

BRCA1 and BRCA2 are genes that produce proteins responsible for repairing damaged DNA. Mutations in these genes can significantly increase the risk of developing breast and ovarian cancers. Understanding these mutations is crucial for assessing cancer risk and determining appropriate preventive measures.

Cancer Prevention Strategies

Women with BRCA mutations can adopt various strategies to reduce their cancer risk, including lifestyle changes such as maintaining a healthy weight, exercising regularly, and limiting alcohol intake. Additionally, they may consider preventive surgeries, such as mastectomy or oophorectomy, and regular screenings to catch cancer early.

Genetic Testing and Counseling

Genetic testing for BRCA mutations allows individuals to understand their cancer risk better. Genetic counseling provides support and information about the implications of test results, helping women make informed decisions regarding surveillance, preventive measures, and family planning.
