A trial comparing 2 different ways of doing a colonoscopy to screen for bowel cancer (CONSCOP)

This trial looked at a way of doing a colonoscopy that involves spraying a blue dye throughout the large bowel. This is called contrast enhanced colonoscopy or chromocolonoscopy.

Everyone that took part had already given a poo (stool) sample as part of the NHS Bowel Cancer Screening Programme in Wales.

The bowel cancer screening programme aims to detect bowel cancer when it is at an early stage and treatment is more likely to work. It can also reduce the risk of bowel cancer developing in the first place by finding and removing small growths called polyps. If polyps aren’t removed, they may develop into cancer.

Cancer Research UK supported this trial.
