If you have a
very strong family history of colon cancer, you may want to talk to your doctor or a
genetic counselor about having a blood test to look for changed genes.
Genetic testing can tell you if you carry a
changed, or mutated, gene that can cause colon cancer. Having certain genes
greatly increases your risk of colon cancer. But most cases of colon cancer aren't caused by changed genes.
