BRCA1 (breast cancer 1)

BRCA1 is a gene that produces a protein important for repairing damaged DNA. When this gene functions correctly, it helps prevent the development of certain cancers, particularly breast and ovarian cancer. However, mutations in the BRCA1 gene can increase the risk of these cancers significantly. Individuals with hereditary BRCA1 mutations may be advised to undergo regular screenings or consider preventive measures, such as surgery or medication, to manage their cancer risk. Awareness of BRCA1 is crucial for those with a family history of breast or ovarian cancer.
