BRCA1 (Breast Cancer 1 gene)

BRCA1, or Breast Cancer 1 gene, is a gene that helps repair damaged DNA in cells. When this gene is functioning properly, it plays a crucial role in preventing the development of cancer, particularly breast and ovarian cancers. However, mutations in the BRCA1 gene can impair its ability to fix DNA, increasing the risk of these cancers. Individuals with BRCA1 mutations may benefit from genetic counseling and screening, as this knowledge can inform treatment and prevention strategies. Understanding BRCA1 can be vital for many in assessing their cancer risks and making informed health choices.
