Increasing rate of colorectal cancer in younger patients: a review of colonoscopy findings in patients under 50 at a tertiary institution.

A total of 1.9% of patients under 50 who underwent colonoscopy were diagnosed with CRC, whilst 21.5% of patients had significant findings. These rates are greater than previously quoted figures and data for patients under 50, and provides evidence to support lowering of the CRC faecal occult blood testing screening age.
