Excellent queries! I think a usual blood examination for colon cancer is the fecal occult blood check (fobt), which checks for secret blood in the stool. but there are on top blood tests that look for specific biomarkers associated with colon cancer, like carcinoembryonic antigen (cea). As for risk factors, I've listened to that certain genetic conditions or a family history of colon cancer might affect the accuracy of blood tests.
