Confocal laser endomicroscopy is newly developed tool to diagnose the digestive diseases without tissue biopsy and tissue pathology,which can realize"optic biopsy"by achieving the highest magnifying imaging of digestive tract membrane.
When a pulse of light is sent into the tumor using fiber optic cable that is threaded into a tumor using a biopsy needle, the molecule absorbs the light energy, converts it electrical energy that then causes tumor cells to self destruct.
