After analyzing data from the US Census Bureau and the CDC National Interview Survey, experts claim that nearly 60% of Americans over 50 face an average risk of colorectal cancer but haven't been screened. To perform a sigmoidoscopy or colonoscopy on all these people would be unachievable so, it would be ideal if people did a blood-in-stool test first and only if this was positive, then have a colonoscopy. This would avoid unnecessary expensive tests.
