Why can't a CT scan see colon cancer well? How large would it need to be to be seen?

Not Designed for it: Not what a ct scan is designed to do. Usually colon cancer will not be clearly evident on ct until it is at stage iii or stage IV level, since it has to anatomically change the colon to be evident on ct. To get that level of change, it needs to be at minimum a locally advanced tumor. Every once in a while it may be evident at the stage ii point, but very low sensitivity. ...Read more

Can I be screened for colon cancer with a CT scan instead of a colonoscopy?

Can I be screened for colon cancer with a CT scan instead of a colonoscopy?

Sometimes: Ct colography is never meant to replace a colonoscopy. At high volumn centers, the detection sensitivity of ct exam is indeed comparable to colonoscopy but you need to know the rate of detection of your imaging facility. Bowel prep is required for both procedures - no way around the unpleasant process. Beware that there is significant radiation exposure with the exam. ...Read more
