Should my family or I have genetic testing?

 

Q: Should my family or I have genetic testing? 

A: You can inherit a higher risk of developing certain cancers. Yet only about 5 to 10 percent of cancers are inherited. Depending upon the type of cancer you have, there may be a screening test that can determine if you carry a genetic mutation that puts you and your close blood relatives at higher risk. 

Genetic testing for cancer risk is still largely in its scientific infancy. Finding a genetic mutation in a test does not mean that person will definitely develop cancer. Discuss the possibility of genetics playing a role in your cancer with your doctor. If  indicated, your doctor will refer you to a genetic counselor to learn about the risks, limitations, and benefits of genetic testing.
