What does a biopsy for Barrett's esophagus involve?

This is often combined with spraying the area with different fluids, such as vinegar, to allow the physician to identify the best areas to biopsy. Specialized endoscopes can also be used to change the light used to see the esophagus to identify areas for biopsy. The biopsies are examined by the pathologist, who looks for microscopic changes in the tissue that show that the cells are becoming more abnormal and cancerous. These changes are called dysplasia.
