What Is the GREAT Program?  

Our team of specialized physicians and advanced practice providers (APPs) is highly experienced in genetic testing. We provide the latest tests and compassionate genetic counseling, empowering you to be proactive with your health.

Your genetic test requires a small blood or saliva sample at one of our clinics. After we receive your results, we offer personalized preventive strategies and treatment options if needed. You can trust us to deliver the support and expertise you need to understand and minimize your cancer risk. 

Our Genetic Counselors

At Texas Oncology, our team of genetic counselors oversee the Genetic Risk Evaluation and Testing (GREAT) program at 79 sites across the state. They have unique roles in training and supporting physicians, physician assistants, and nurse practitioners to provide high quality genetics services to patients in their own communities. A genetics appointment at Texas Oncology will be scheduled with a provider who is designated to offer genetic evaluations and who has the immediate support of the genetic counseling team. Your provider will determine if it is necessary to have a certified genetic counselor present for an appointment. Find a GREAT Program provider near you.

What Can I Expect With Genetic Testing?

If you’re considering genetic testing, you may have many questions and emotions. We understand and take the time to address your concerns, so you feel confident in your choice. Here’s what you can expect with the GREAT Program:

Consultation before your genetic testing

Before we begin testing, you will receive a consultation with a GREAT provider. We discuss:

• Your personal and family medical history of cancer
• Benefits and limitations of genetic tests
• Insurance coverage and any out-of-pocket costs

The day of your test

If you choose genetic testing, you will have a separate appointment for your test. Usually, we only need to collect one small sample of blood. We send the sample to a specialized lab for evaluation. In most cases, we receive your results within 2 to 3 weeks.

Receiving your results

After receiving your genetic test results, our providers carefully review and discuss the findings with you. We take the time to help you understand what the results mean for your health. We also provide emotional support and guidance on next steps or further testing if needed.

Frequently Asked Questions

My genetic tests were positive. What does this mean for me and my family?

It can be stressful to learn you have a genetic abnormality linked to cancer. However, a positive result does not mean you will get cancer. We discuss your risk and recommend screenings and procedures that help detect cancer early, when treatment is more successful.

I received a negative result. How should I move forward?

Negative test results mean you don’t have any known genetic abnormalities that cause an increased cancer risk. Our team will talk with you about regular screening and cancer prevention strategies.

Do genetic tests detect all genetic mutations?

Experts already know about thousands of genetic abnormalities, and new ones continue to be discovered. Current genetic tests can successfully identify known mutations, but it is possible to have a mutation that has not yet been identified.
