Endoscopy

This procedure is used to look inside the body for any abnormal areas. It is done with an endoscope – a thin, flexible tube with a light and camera on the end. The endoscope is put into the body through a natural opening (such as the mouth) or a small cut made by the surgeon. The camera projects images onto a monitor so the doctor can see inside the body. If they see something suspicious, they can also take a tissue sample (biopsy) using the endoscope.
