5. How Barrett's Esophagus Is Diagnosed

Barrett's esophagus is diagnosed with an upper endoscopy. In this procedure, the doctor uses a flexible tube with a camera called an endoscope to assess the lining of the esophagus, stomach, and duodenum. The doctor can collect tissue samples for biopsy during the procedure if needed. A pathologist will examine this tissue under a microscope and look for abnormal cell growth, which can indicate a risk of cancer.
