DNA Tests Provide Information about Health Risks

DNA tests can also reveal important health risks. There are at-home DNA tests available for several hereditary cancers, including breast, ovarian, and prostate cancer. There are also tests for genes linked to cardiovascular disease and Alzheimer's.

These tests can be beneficial, especially if you have a family history of these conditions. They can also warn you about potential future medical conditions so you can take preventative measures right away. However, at-home DNA tests are not a substitute for a comprehensive medical evaluation. Remember that they only look at your genes, not what's going on in your body.
