Doctors often test people at high risk for esophageal cancer. This includes individuals with Barrett’s syndrome. One esophageal cancer test is the barium swallow test, where a person swallows a thick barium mixture and then undergoes an x-ray. Barium coats the esophagus and shows clearly on the x-ray, highlighting any irregularities. Other tests include MRI scans, endoscopies, and CT scans.
