How is Lynch syndrome diagnosed?

ANSWER

Your doctor will take a detailed family history to see how many of your relatives have ever had colon cancer. If you’re high risk, your doctor will send you for genetic counseling and DNA testing. If one person in your family is diagnosed with Lynch syndrome, your other relatives may want to get tested.
