When should you use endoscopy over colonoscopy?

Endoscopy refers to an exam using lighted a scope that is inserted into a hollow part of an organ or body part for evaluation. A colonoscopy is a type of endoscopic procedure.

Colonoscopy is for colon cancer screening. Endoscopy is to evaluate the stomach.

Thanks for the question. There is actually a big difference between colonoscopy and endoscopy. When we say "endoscopy" what we usually mean is "upper endoscopy" meaning we are taking a look at the insides of your stomach and esophagus. Although a colonoscopy, which looks at your colon, is technically an "endoscopy," we usually call it a colonoscopy or "lower endoscopy" to keep things clear.
