Colorectal cancer often starts with subtle digestive changes. Know the early and advanced signs, what tests clinicians use, and why screening (starting at age 45 for average-risk adults) is key to early detection and prevention.
Virtual colonoscopy (CT colonography) uses low-dose CT and 3D imaging to screen the colon with less invasiveness than conventional colonoscopy. It detects polyps and cancers but cannot remove lesions - positive findings require traditional colonoscopy.
