The esophagus is the muscular tube that connects the throat to the stomach. Cancer of the esophagus starts from its inner layer and grows outward, originating in either the squamous cells that routinely line the inner surface of the esophagus or glandular tissue that develops within the esophagus.
The American Cancer Society has indicated that an estimated 15,560 cases of esophageal cancer are expected to be diagnosed in 2007. The number of deaths from esophageal cancer is estimated to be 13,940 in 2007.
