endoscopes and endoscopy
There are many types of endoscopes, each named according to the organ or area it is used to examine. For example:
Small instruments can be inserted through an endoscope and used to take samples of (biopsy) suspicious tissues.
There are many different reasons to perform an endoscopy. For example, a doctor may order an endoscope if a patient has bleeding, pain, difficulty swallowing, or a change in bowel habits. Colonoscopy is also done to screen for colon polyps and colon cancer. (See also sigmoidoscopy.) Endoscopes also can be used to treat certain diseases or conditions. For example, tumors can be removed or bleeding from lesions can be stopped.
