Barrett’s esophagus


A condition in which cells that line the lower part of the esophagus (the tube through which food passes from the throat to the stomach) change into or are replaced by abnormal cells. It may be caused by stomach acid backing up into the esophagus over time (gastroesophageal reflux disease or GERD).

Barrett’s esophagus is associated with an increased risk of developing esophageal cancer.
