How many different kinds of esophageal cancer are there?

There are two different kinds of esophageal cancer, and they are based on which cells (tiny structures that make up body structures) of the esophagus they affect. Squamous cell carcinomas are esophageal cancers that most often affect the cells that make up the lining of the esophagus in the area closer to the mouth. In contrast, adenocarcinomas are esophageal cancers that affect the cells that make esophageal fluids, such as mucus. Adenocarcinomas most often begin in the area of the esophagus closer to the stomach, and it is the most common type of esophageal cancer in the United States.
