The time between colonoscopies could be extended, study suggests

It’s recommended that adults with average risk for colorectal cancer get a colonoscopy every 10 years, but a new study indicates that that time period could be safely extended. The study, which relied on a screening registry of more than 165,000 people, found that having one negative result with a high-quality colonoscopy was associated with a greatly reduced risk of getting and dying from colorectal cancer over more than 17 years. Past studies have hinted at similar findings, but the new research followed more people for a longer time than earlier reviews.
