DNA testing may help unlock secrets of your genetic code

23andMe offers inside look at your DNA

DETROIT - If you had the ability to look into the future and learn what medical problems you may encounter down the road, would you want that information today?

DNA testing is making it possible for people to learn more than ever before about their own health.

Some of these tests are now inexpensive and they're being heavily marketed but are they a scam?

It's a simple test that could unlock secrets about your own health, but does DNA testing cause more harm than good?

Angelina Jolie made headlines around the world when it was revealed she elected to have a double mastectomy, after learning through DNA testing she was at a high risk to develop cancer.

DNA testing is no longer reserved for the rich and famous, as everyone can learn clues about their genetics thanks to a test like the one offered by 23andMe.

Costing $99, the goal is to give you an inside look at your DNA, revealing your potential risk for hundreds of diseases, certain cancers, Parkinson's disease, Alzheimer's and more.

People can use the information to make lifestyle changes that could help change their future. This information is also key for certain people who may inherit certain conditions.

The test itself is simple and painless. Once that's done, you simply seal up the tube, package it up, register online and then wait roughly 6 weeks for the results.

Local 4 medical expert Dr. Frank McGeorge said the concern with some testing like this is that it is relatively new and even medical experts don't know what it all means.

Another big concern is that some people may not know how to process this information.

The 23andMe team does offer one-on-one counseling, and with each test gives recommendations about what you can do to cut down your risk of developing certain diseases.

Additionally, 23andMe could help you get answers to some questions and learn more about yourself, but remember that there are no guarantees even when it comes to your own DNA.
