Cancer - esophagus
Esophageal cancer is a cancerous (malignant) tumor of the esophagus, the muscular tube that moves food from the mouth to the stomach.
See also: Barrett's esophagus
Esophageal cancer is not very common in the United States. It occurs most often in men over 50 years old.
Two main types of esophageal cancer exist: squamous cell carcinoma and adenocarcinoma. These two types look different from each other under the microscope.
Squamous cell esophageal cancer is linked to smoking and alcohol consumption.
Barrett's esophagus, a complication of gastroesophageal reflux disease (GERD), increases the risk for adenocarcinoma of the esophagus. This is the more common type of esophageal cancer. Other risk factors for adenocarcinoma of the esophagus include:
