Information: Hereditary genetic testing for personal risk of cancer

Hereditary genetic testing looks at your DNA to see if you were born with gene changes (mutations) that can increase your risk for certain diseases, like breast cancer, colon cancer, or heart conditions.

How to get tested?

Talk to your primary care provider (PCP) Tell them, “I’d like to talk about genetic testing.”
They will review your personal and family health history to see if testing makes sense for you.

Meet with a genetic counselor (if available).
A genetic counselor is a specialist who explains:

    • What the test looks for
    • What your results could mean
    • Whether your insurance covers it
      This step helps you decide if testing is right for you.

Give a sample.
Testing is usually done with either:

  • A blood draw, or
  • A saliva (spit) sample

The sample is sent to a lab that looks for genetic changes linked to inherited conditions.

Get your results.
Results usually come back in a few weeks.
Your provider or genetic counselor will explain:

        • Whether a gene change was found
        • What it means for your health
        • Whether your family members should also be tested
        • What follow-up care or prevention steps you may need

Where you can get tested?

  • Your primary care provider
  • OB/GYN or cancer specialist
  • A genetic counselor
  • Hospital or health system specialty clinics

Cost

Insurance often covers genetic testing if you meet certain criteria (like a strong family history). Your doctor or genetic counselor can check your insurance coverage first. Low-cost programs are sometimes available if you qualify.

Important

Genetic testing starts with a simple conversation. Your doctor or a genetic counselor can help you understand whether testing is right for you and what the results could mean for your health.
