Most scientists in the field concur on how cancer evolves in the esophagus. The commonly accepted pathway for progression from normal squamous epithelium to cancer starts with reflux-associated esophageal damage (GERD), then advances to intestinal metaplasia (early Barretts esophagus), followed by low- and high-grade dysplasia (Barretts esophagus), and finally adenocarcinoma.
