Gene Testing for Breast or Ovarian Cancer
At Middlesex Hospital, we’re not satisfied with simply diagnosing and treating cancer. Our goal is to use the latest technology to identify those who may be most susceptible, and then help them reduce their risks before the first cancer cells even have a chance to develop.
Our breast cancer gene testing program uses DNA analysis to look for alterations in either of the two “breast cancer genes,” known as BRCA1 and BRCA2 the most common cause of hereditary breast and ovarian cancers. Although these alterations are uncommon—they’re only responsible for about 5% of breast cancers and 15% of ovarian cancers—women who have inherited them face a much higher risk of developing breast or ovarian cancer during their lifetimes. In addition, our breast cancer gene testing program uses DNA panel genetic testing to look for alterations in other genes associated with an increased risk for breast cancer, for example TP53, ATM, CHEK2, PALB2, BRIP1 and others.
If you are a candidate for genetic testing, this simple blood test will let you know if you do have a gene alteration associated with increased risk for breast cancer. Then, based on your results, a genetic counselor will be able to provide you with an estimate of your risk for breast or ovarian cancer.
