What about testing for colorectal cancer using newer technology, such as virtual colonoscopy, fecal immunochemical testing (FIT or iFOBT), and stool DNA testing?
Although virtual colonoscopy and stool DNA testing are used in some medical settings, data are not yet sufficient to support these tests for colorectal cancer screening. Research is underway to evaluate their effectiveness as screening tests, especially compared with the screening tests already recommended for colorectal cancer. Virtual colonoscopy, also called computed tomographic (CT) colonography, uses multiple CT images to create a three-dimensional view of the colon. As is the case with traditional colonoscopy, a patient must prepare for virtual colonoscopy by drinking a strong laxative to clean out the colon thoroughly. During virtual colonoscopy, air is pumped into the rectum to expand the rectum and colon. If a polyp or other abnormality is found, it cannot be removed during this procedure. A follow-up colonoscopy will be necessary to remove polyps or take tissue samples for further analysis. Because virtual colonoscopy is still considered experimental, most insurance plans do
