Colon cancer has been America’s second biggest killer.  The use of colonoscopy has scared many people from colon cancer screening.  The use of X-ray colon cancer is cheaper and less invasive than the colonoscopy.  The success rate of the new ‘virtual colonoscopy’ a.k.a. computed tomogrpahic (CT) colonography in detecting colon cancers or abnormal growth, which are detected by normal colonoscopy, is as high as 90%.  However misinterpretation of the X-ray can lead to the spotting of polyps, therefore follow-up results are needed to confirm the analysis.  There are other drawbacks of this new technology in detecting colon cancer which need to be further investigated and improved.
