What percentage of breast cancers are linked to gene mutations?
About 5% to 10% of breast cancer cases are thought to be hereditary, meaning that they result directly from gene changes (mutations) passed on from a parent.
Can genetic test determine breast cancer risk?
Genetic testing for hereditary breast and ovarian cancers looks for mutations in the BRCA1 and BRCA2 genes. Your genetic counselor may suggest testing using a multigene panel. A multigene panel looks for mutations in several genes, including BRCA1 and BRCA2, at the same time.
What is the most common genetic mutation in breast cancer?
BRCA1 and BRCA2 gene mutations are currently the best-known and most discussed genetic risk factors, but new genetic links are being discovered regularly. Below are a number of other genes that are known to influence breast cancer risk.
What are the genetic variants associated with breast cancer?
Those include BRCA1 and BRCA2, which occur in about one of every 500 women and confer an increased risk of breast or ovarian cancer, and rarer mutations in a gene called TP53 that causes a disease called Li Fraumeni syndrome, which predisposes to childhood and adult-onset tumors.
