Can the cecum be seen during a colonoscopy? Or is it through a sigmoidoscopy? Can cancer of the cecum be detected through radiology tests like ct/mri?
Yes-No-Maybe: Colonoscopy evaluates the entire large intestine, from cecum to rectum. Flexible sigmoidoscopy only goes as far as the left side of the colon, nowhere near the cecum. Routine ct scanning may identify a (large) cecal tumor but is much less sensitive than a colonoscopy; ct colonography is almost as sensitive as a colonoscopy, but is less desirable than colonoscopy since a biopsy cannot be done. ...Read moreSee 3 more doctor answers

Colonoscopy remains the gold standard for detecting colon cancer. ...Read moreSee 1 more doctor answer
