Breast Cancer Genetics

Genes pass hereditary information from generation to generation. Certain gene mutations can increase breast cancer risk.

Genetic Testing for Breast Cancer Genetic testing through a simple blood or saliva test is recommended for individuals who want to know if they carry a breast cancer gene mutation.

BRCA: The Breast Cancer Gene A BRCA gene mutation occurs when the DNA of that gene becomes damaged, or mutated. About 0.25% of the population carries a BRCA gene mutation.

Other Breast Cancer Genes In addition to BRCA genes, other genes that increase the risk of breast cancer include PALB2, CHEK2, CDH1, PTEN, STK11, TP53, and more.

What To Do If You’ve Tested Positive Those with a breast cancer gene mutation may consider creating a custom early detection plan, preventative surgery, and more.
