Barrett's esophagus is a change in the lining at the end of the esophagus. The esophagus is the tube from the throat to the stomach. Heartburn for more than five years in males is a risk factor. Having Barrett's esophagus increases the risk of esophageal cancer. Biopsies are obtained from a suspected area during upper endoscopy. The pathologist will classify the tissue as nondysplastic, low-grade dysplasia, or high-grade dysplasia. The risk of cancer progression per year is 0.2 to 0.5 % for nondysplastic, 0.7% for low-grade dysplasia, and 7% for high-grade dysplasia. Patients with nondysplastic Barrett's esophagus would need a repeat upper endoscopy with biopsies in 3 to 5 years.
