Colon cancer genetic
testing is a blood test that looks for the changed (mutated) genes that cause
colon cancer. Although most people who get colon cancer do not have one of
these mutated genes, having them greatly increases your chance of getting colon
A positive result means that you may have one of the
changed genes that causes FAP or HNPCC. It also means that, without treatment, your chances of
getting colon cancer are very high.
If you have a positive result, you will be able to take action that may help you and your family members live longer. This includes starting screening at a younger age and having screening tests more often.
A negative result means that none of these
genes were found in your blood sample.
