US Multi-Society Task Force identifies three tiers of CRC screening options for average-risk patients
posted: Jul. 05, 2017.
Tier one options are considered the “cornerstones of screening” and include colonoscopy every 10 years. The task force, which includes the American College of Gastroenterology, called for black Americans to begin CRC screening at age 45 and acknowledged the trend of higher rates of CRC in adults younger than age 50 is a "major public health concern."
