Genetic Testing

What is Genetic Counseling?

Your genes may predict your risk of cancer, and certain genetic tests may help your doctors provide better screening or treatment options. If you have certain types of cancers, or cancer in your family, you may be at higher risk.

Hereditary Cancer

All cancers are caused by the accumulation of genetic mutations, but not all cancers are caused by an inherited genetic mutation.  About 5-10% of cancers are caused by an inherited genetic mutation. Genetic counseling may be recommended for families with a pattern of certain cancers (breast/ovarian or endometrial/colon) or cancer at younger ages, to see if the cause was inherited.

There are also families who have multiple people with cancer but no identifiable genetic mutation. In these cases, the cancer is familial, likely due to a combination of shared environment and shared genetic factors.  Members of these families may still be at a higher risk of cancers even with negative results during the genetic testing process. For these reasons, it is important to know your family cancer history and to share this information with your healthcare providers. A healthcare provider can then decide whether you need increased screening based on family history alone.
