Adults, beginning at age 50 years and continuing until age 75 years.

The risks and benefits of these screening methods vary.
Certain factors increase your risk for colorectal cancer and may call for earlier or more frequent screening. People with a close relative diagnosed with colorectal cancer before age 60 should begin screening at age 40 -- or 10 years earlier than the age the relative developed cancer.he American College of Gastroenterology further advises that African-Americans begin screening at age 45 due to increased risk.
