Genetic Counseling and Testing Team

Genetic testing for breast cancer is an important part of any comprehensive breast center. Our medical oncologists who specialize in genetics and high risk patients, along with our genetic counselors, are experienced in guiding families through the genetic testing process. They also are up to date on the most recent methods for helping patients manage the knowledge that they have a genetic predisposition for developing breast cancer.

We strongly believe in the importance of genetic counseling before performing any testing, so that the ramifications of the results (positive or negative) are understood. Our team helps the patient make informed decisions upon learning her results.
