Genetic Screening

Your genes play a major role in how cancer develops. At Good Samaritan Medical Center, genetic screening plays an equally big role in treating your cancer. By learning about your genes, we can determine your risk for certain types of cancer, including colon cancer and ovarian. 

The Cancer Genetics Program at Good Samaritan’s Cancer Institute involves education about hereditary cancer and a detailed evaluation of your family’s medical history.

What is included in Genetic Testing?

Hereditary Risk Assessment – During your initial evaluation period, you will fill out a family history questionnaire, which includes questions regarding your personal and family history of cancer.

How it Works – Genetic testing consists of a mouthwash or blood test. Analysis of the sample can determine if you inherited a gene mutation that may increase your cancer risk.

Results of Genetic Testing – Genetic testing can help you make informed decisions about how to manage your future healthcare. Test results can help your health care provider develop a plan of care just for you and also be of great value to family members. Before and after genetic testing, you may have a genetic counseling session.

Genetic Counseling – During your genetic counseling session, our genetics counselor will help simplify the complex concepts into terms you can understand. The goal is to provide clear information about genetic risk factors and address your questions and concerns.
