Depends: If you mean a regular ct with contrast (and not a virtual colonoscopy), the answer is occasionally. If the cancer is spread, you may see enlarged nodes or metastases. If not spread, you could conceivably see obstruction or changes in the bowel wall but it would likely be a big tumor nonetheless. A ct is not a screening test and is not the way to diagnose early colon cancer.
