After the screening age for colonoscopy was lowered in colorectal cancer (CRC) guidelines, younger people were more likely to undergo the procedure, researchers found.
Among people ages 45 to 49, first-time screening rates increased from 3.5% in the period before guidelines were changed to 11.6% after they were updated (relative rate [RR] 3.36, 95% CI 2.45-4.61), reported Uri Ladabaum, MD, MS, of Stanford University School of Medicine in Redwood City, California, and colleagues in Clinical Gastroenterology and Hepatology.
