Colon Cancer Genetic TestingColon Cancer Genetic TestingHow 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. Medical Review: E. Gregory Thompson, MD - Internal Medicine Kenneth Bark, MD - Surgery, Colon and Rectal Last Updated: August 27, 2012 |
