Ask yourself why you are doing this. Before seeking genetic testing, it's important to think about all of the possible emotional and economic consequences for you and your family, says Dr. Daly. Consider how genetic testing might affect you or your children's ability to get insurance or find employment, Dr. Daly says. Imagine how it might affect your relationship with your sister, daughter, or spouse. Think about what you will really do with this information.
Some people do nothing.
Some begin getting more frequent checkups to detect these diseases early. Others opt for preventive surgery to remove cancer-prone organs, Dr. Daly says. Imagine how you might react to positive test results. Take time to seriously contemplate these issues before making a decision to undergo testing. A certified genetic counselor will help you to understand the risks and benefits of genetic testing for you.
