I often write about the importance of prevention when it comes to protecting your health. Routine health screenings are one of the most effective tools we have for catching problems in the early stages, before they become big problems. I recently discussed colonoscopy, the test used to screen for colorectal cancer. Today I will explain endoscopy, a related procedure that can help prevent esophageal cancer.
Endoscopy is a procedure performed by a gastroenterologist, usually done in an outpatient facility. It is used to examine the esophagus, stomach and duodendum (the first portion of the small bowel) using a thin, flexible scope (endoscope) with a light on the end. The doctor may look directly through the scope or view the inside of your body on a monitor.
