Endoscopy is a minimally invasive procedure used to identify and determine how to best treat conditions that appear in the upper or lower part of the digestive system. Endoscopy is the best means of early detection for several forms of cancer.

Endoscopy can be used to view the esophagus, stomach, colon, ear, nose, throat, heart, urinary tract, joints and abdomen.

An endoscope is a thin tube with powerful light and a tiny camera. The length and flexibility of the endoscope depends on the part of the body being examined. An endoscope can also be equipped with forceps to collect tissue samples or remove a suspicious growth, a cytology brush for taking cell samples or suture removal forceps for removing stitches inside the body.
