ABSTRACT

Major advances in the understanding of the molecular basis of cancer have made it

possible to identify families where breast cancer risk has a strong inherited basis.

Individuals who perceive themselves to be at high cancer risk are increasingly seeking out

clinical genetics services that assess their cancer risk and provide management

recommendations. Physicians are also increasingly referring patients for genetic testing,

since identification of genetic risk may influence certain patient treatment choices both

around the time of diagnosis, such as whether to have prophylactic surgery as part of their

definitive treatment, and during long-term management. Comprehensive cancer genetics

clinics, often involving oncology and genetics professionals, offer these services to

individuals largely concerned about the implications of their family history of cancer. In

addition, clinicians in many specialties are being called upon by their patients to provide

information about genetics and cancer risk.
