Breast Cancer 2 (BRCA2)

BRCA2 is a gene that produces a protein essential for repairing damaged DNA, helping to prevent cells from becoming cancerous. When BRCA2 has a mutation or defect, its ability to fix DNA damage is compromised, increasing the risk of developing breast and ovarian cancers. These mutations can be inherited, meaning they run in families, and carriers may face a higher chance of cancer over their lifetime. Understanding BRCA2 helps in assessing cancer risk, guiding preventive measures, and choosing targeted treatments effectively.
