BRCA1 and BRCA2
Genes whose mutations significantly raise the risk of breast and ovarian cancers.
What it is
BRCA1 and BRCA2 are genes that help our bodies repair damaged DNA. When these genes have mutations, they can't do their job properly, which can lead to cancer. This is especially true for breast and ovarian cancers, but it can also increase the risk of other types of cancer.
How it works
In normal cells, BRCA1 and BRCA2 help fix mistakes in DNA that can cause cancer. When these genes are mutated, the cell's ability to repair DNA is impaired, which can lead to uncontrolled cell growth and cancer. In some cases, this can be passed down from parent to child, making it a hereditary risk factor.
Why it matters
Understanding BRCA1 and BRCA2 mutations is important because it can help doctors identify people who may be at higher risk of developing certain cancers. This information can inform decisions about cancer screening, prevention strategies, and treatment options. It can also help researchers develop new ways to prevent and treat cancer.
