BRCA1 mutation

A BRCA1 mutation is a change in the BRCA1 gene, which normally helps repair DNA and prevent cancer. When this gene is mutated, it may not work properly, increasing the risk of developing certain cancers, especially breast and ovarian cancer. People with a BRCA1 mutation have a higher likelihood of developing these cancers compared to the general population. It can be inherited from a parent and can be identified through genetic testing. Knowing about this mutation helps in making informed choices about cancer screening and prevention strategies.
