By contrast, the cells that comprise the bulk of most tumours lack these surface proteins and are poor at creating new tumours.

We would learn how to create a reflection on a metal surface through the use of the Clone Stamp tool and a lot more like softening the images contrast but still leaving the edges sharp.

NBI changes the white light normally emitted by the colonoscope to a bluish light, providing a narrower wavelength and enhancing visual contrast of the surface structure of the colon.
