    Colon Cancer Genetic Testing - How Accurate Is the Test?

    Although these blood tests are highly reliable, no test is 100% accurate. The test cannot tell you when or whether you will develop colon cancer. Testing negative for an inherited colon cancer gene does not mean you will never get colon cancer. It means your risk of colon cancer is about the same as that of the average person.

    There are many different genetic mutations that can lead to FAP or HNPCC. Genetic testing does not find all of them. Because of this, a person may have a normal genetic test but still have an increased chance of having an inherited colon cancer.

    Lynch Syndrome: Get the Facts

    Lynch syndrome is a genetic condition that makes people more likely to develop certain cancers. People who have it also have about a 50% to 80% chance of getting colorectal cancer by age 70. They’re also at risk for cancers of the uterus, ovaries, and stomach. And they tend to get cancer at younger ages than other people, often in their 30s and 40s. Lynch syndrome is sometimes called hereditary non-polyposis colorectal cancer (HNPCC), Muir-Torre syndrome, and Turcot syndrome.
