Genetic Testing

Approximately 5-10% of breast cancer is genetic in origin. An additional 10% is familial. We have isolated twenty genes that have been shown to increase the risk of breast cancer with variable penetrance in carriers. Examples include BRCA1, BRCA2, and PALB2.

It takes just one tube of blood to determine if you are a carrier of one of these mutations. Most insurance companies cover the costs. There are federal and state laws in place to protect patients against discrimination if your results are positive. 
Women who should be counseled and possibly tested include those with a:

  • Personal history of breast cancer under the age of 50
  • Personal history of ovarian cancer
  • Ashkenazi Jewish descent with a family history of breast or ovarian cancer
  • Family history of multiple relatives with either breast or ovarian cancer
  • Family history of male breast cancer
  • Family history of bilateral (left and right) breast cancer
  • Family history of premenopausal breast cancer

If you fit into any of these categories or would just like to know more, contact our office at (561) 482-8887.
