Screening guidelines for colorectal cancer have changed over time. Most medical groups today recommend patients get a colonoscopy to detect polyps, often in addition to an annual fecal exam. "A colonoscopy is really the preferred screening tool. Colonoscopies are not just for cancer detection; they're also for cancer prevention. It's a diagnostic and therapeutic tool because it detects polyps and can remove them," one colorectal surgeon said.
