Upper endoscopy for esophageal cancer

Upper endoscopy is one of the most accurate ways of diagnosing esophageal cancer. It may be used as a biopsy, as well as to determine the extent of the tumor.

The camera on the end of the endoscope allows doctors to see the lining of the esophagus and detect abnormalities. The procedure is performed while the patient is under sedation.

What is an upper endoscopy?

Upper endoscopy is a procedure that involves the use of an endoscope (a thin, tube-like device equipped with a camera), to examine the upper digestive system. In an upper endoscopy, the endoscope is inserted into the body through the mouth to look for signs of illness in certain areas, such as the esophagus, stomach and start of the small intestine (bowel).
