Genetic Counseling and Testing

The Cancer Genetics Program provides expert care for patients with a recent cancer diagnosis or a personal history of cancer, as well as for individuals who have a family history of cancer. Genetic testing can help identify hereditary causes of cancer. Results can be used to inform treatment decisions and options for early detection and cancer prevention for those at a heightened risk of cancer.

Who Should Consider Genetic Counseling for Cancer? 

Approximately 10-15% of all cancers are caused by genetic risk factors. Families with inherited cancer syndromes often have several family members, across multiple generations, who have had cancer.

What is genetic testing?

For patients that are offered genetic testing, a small blood or saliva sample is collected. This sample can often be collected at the time of the genetic counseling visit. The sample is then sent to a laboratory for analysis. Depending on the test ordered, results are generally available in 4 weeks. The genetic counselor receives the results from the laboratory, and results are shared with each patient by telephone and/or in person. All patients also receive result letters and a hard copy of their result for their records.  

Preparing for genetic counseling and testing FAQ

How should I prepare for my appointment? 

In advance of your appointment, it is very helpful to collect and provide the following information:    

  • Your own cancer history, specifically any diagnoses of cancer you may have had 
  • Cancer diagnoses in your relatives including cancer type and their ages at diagnosis 
  • Has any relative had cancer genetic testing? If so, please provide a copy of the test report when possible 

You will be asked to complete medical history and family history forms in advance of your appointment.   

What can I expect at my appointment? 

A visit usually includes an hour-long meeting in person or via telemedicine with a board-certified genetic counselor. In most instances patients also meet with a physician during this appointment. All of our genetic counselors and physicians have expertise in inherited cancer syndromes.  

The evaluation includes: 

  • A detailed review of the family medical history 
  • Review of personal medical history and risk factors 
  • Cancer risk assessment and education about genetic syndromes 
  • Genetic testing, when indicated, and interpretation of the results

Genetic counseling and genetic testing services are billed separately. Your genetic counseling appointment is billed to your insurance as an office visit.  Genetic testing is billed to your insurance by the commercial testing laboratory. Most insurance companies cover genetic testing costs for patients meet criteria based on personal or family history of cancer.
