What is Genetic Testing?

How is Cancer Genetic Testing Done?

Genetic testing is ordered by a physician, advanced practice provider or genetic counselor. Testing is usually done through a routine blood draw or saliva sample once you have signed a consent form. Technicians will look for specific abnormalities in your genes associated with an inherited cancer syndrome. Results usually return in 2 to 3 weeks and are reviewed with the genetic counselor during a post-test follow up appointment. Results are then shared with your doctor.

Should I Get Genetic Testing for Cancer?

While testing is beneficial in understanding your risks of inherited cancers, not everyone is an ideal candidate. Genetic cancer testing is used to determine if you have specific genetic mutations that can be inherited through a gene; many of which occur in families with specific medical histories.

What Types of Cancer Can Be Determined By Genetic Testing?

There are 50+ types of hereditary cancer syndromes, but the two most common types that can be detected by cancer genetic testing are:

1. Hereditary Breast and Ovarian Cancer Syndrome most commonly related to breast cancer, ovarian cancer, fallopian tube cancer, pancreatic cancer, melanoma, and prostate cancer
2. Lynch Syndrome most commonly related to colorectal cancer

Pros and Cons of Genetic Testing

There are definitely benefits for getting tested for hereditary cancer syndromes, but you should also be aware of the limitations that can occur. For example a positive result, doesn’t mean that you will necessarily develop cancer; however, if a positive result is going to weigh heavily on you and increase stress and anxiety, you need to make this part of your consideration before testing.
