BRCA Gene Testing
Services Performed at: Davison, Lapeer, and Petoskey
Understanding your genetic predisposition to breast cancer can help you and your doctor make more informed decisions about your health. Whether or not you have already been diagnosed with breast cancer, it might have further important implications for you and your family. Women who carry a BRCA gene mutation and know about it can start cancer screening at an earlier age, take risk-reducing medication, or elect to undergo preventive surgery.
Most women who carry the BRCA gene mutation are unaware that they do, yet this genetic mutation in either the BRCA1 or BRCA2 genes increases a woman’s lifetime risk of breast cancer from 12% to up to 85%. The BRCA gene is found in the cells of breast tissue, where it helps repair damaged DNA or destroy cells when DNA can’t be repaired. If the BRCA gene itself is damaged, it cannot function properly and allows the damaged DNA cells to duplicate without control, resulting in an almost guaranteed development of a breast cancer at some point during the woman’s life.
