Approximately 5 to 10 percent of individuals with cancer have a hereditary form of cancer or predisposition to cancer. This is the result is the result of changes in genetic information that then predisposes a person to certain types of cancer. These changes in your genes can be passed on from generation to generation.
The Cancer Genetics Clinic at Sarah Cannon Cancer Institute at Henrico Doctors’ Hospital is designed to educate and counsel women and men about their individual risk for certain cancers based on their family cancer history. Identifying these causes of certain hereditary cancers and genetic disorders helps doctors find ways to manage a person’s risk of cancer and ability to treat hereditary cancer syndromes.
If you meet specific criteria for testing, our DNA testing specialists will collect a sample of your blood or saliva and send it to a special genetic laboratory for testing. Following testing or counseling, the clinic will develop a plan to help reduce your risk for cancer and begin or continue screenings for early detection of cancer.
An appointment with the Cancer Genetic Clinic requires a physician referral. Physicians can refer patients to our clinic, and we will call the patient to schedule an appointment for DNA testing.
