Scientists develop 'rear-view mirror' to spot bowel cancer

The Third Eye Retroscope provides an additional video camera which gives a rear-facing view to reveal the areas behind folds that are hidden from the front-facing view of the colonoscope.

The device developed by US scientists is used along with a standard colonoscope to improve detection, the 'Daily Mail' reported.

The device is contained on a J-shaped attachment fixed to the tip of the colonoscope. Studies show having that extra view significantly improves detection rates
