What is an endoscopy used to diagnose esophageal cancer?

A doctor uses an endoscopy to actually look at the inside of your esophagus. Prior to beginning the procedure, the esophagus will be numbed with a medication, and the person will be given a tranquilizer. A thin tube containing a light and a camera is then guided down the person's throat. The camera allows the doctor to see the lining of the esophagus and any abnormalities that might be present. An endoscopy can also be used to look at the stomach and upper intestine. The procedure is sometimes referred to as EDG (short for esophagogastroduodenoscopy).
