To a lot of people, genetic testing still sounds like futuristic fiction. And that means people come to us with different misconceptions of what genetic testing is all about.
To help address some of those perceptions, we’ll start blogging from time to time about common myths that surround genetic testing and try to set the record straight.
Here’s one misconception our genetic counselors often hear:
Myth: My DNA is my destiny, and I don’t want to know.
Fact: Your DNA indicates your genetic risks. But for most of us, those risks don’t define your future. There’s a lot you can do to reduce them. Here are just a few examples:
- If you learn you have a genetic predisposition towards common serious health concerns such as type 2 diabetes or heart attack, you get extra motivation to make lifestyle choices that counteract those risks and help prevent these conditions.
- If you learn that you are at increased genetic risk of certain cancers, you know what to watch for, letting you and your doctor start a plan to help you prevent cancer or catch it earlier, when it is usually far easier to treat.
- If you find out you have a genetic predisposition toward vision conditions such as glaucoma, you can start screening earlier – and catch problems before they become serious.
Once you know all the ways you can take action, chances are you’ll want to learn about your DNA.
What are some other genetic myths you’ve heard? Let us know.
