A 54-year-old man presents with dysphagia, heartburn, belching, and epigastric pain. A barium swallow shows a sliding hiatal hernia and a stricture situated higher than usual in the mid-esophagus.

A biopsy shows columnar epithelium at the affected area and normal squamous epithelium above, confirming the diagnosis. What statement is TRUE regarding this condition?
