There are 2 types of esophageal cancer: squamous cell carcinoma (SCC) and adenocarcinoma (AC). Despite the large proportion of SCC cases worldwide, AC is increasing rapidly in North America, Europe and Oceania. The cause of AC is linked to gastroesophageal reflux disease. AC develops as the inner lining of the esophagus is irritated by stomach acid flowing back into the esophagus and is replaced by cells similar to the cells lining the stomach.
