Endoscopy (Mirroring), In endoscopy, a thin, usually flexible tube is inserted over a natural body opening (eg mouth, anus). It is equipped with a light source, a mirror and a camera with which images from the inside of the respective organ are transferred to a monitor. The method is suitable, for example, for the examination of colon (colonoscopy = colonoscopy), stomach (gastroscopy = gastroscopy), bladder (cystoscopy) and lung (bronchoscopy).
Even the slightest changes are discovered, long before symptoms occur. In addition, tissue samples can be taken from suspicious areas during endoscopy and examined under the microscope. As a result, the endoscopy, for example in the intestine, is also suitable for the prevention of cancer: precursors of colorectal cancer are detected and removed immediately, so that no cancer can develop therefrom
