Overview
Classification
Esophageal cancers are typically carcinomas, which arise from the epithelium, or surface lining of the esophagus. Most esophageal cancer fall into one of two classes: squamous cell carcinomas, which are similar to head and neck cancer in their appearance and association with tobacco and alcohol consumption, and adenocarcinomas, which are often associated with a history of gastroesophageal reflux disease and Barrett's esophagus.The adenocarcinomas of esophagus present clinically as that of gastric adenocarcinomas and make up more than 70% of esophageal cancers.[1]
