Cancer - esophagus
Esophageal cancer is not common in the United States. It occurs most often in men over 50 years old.
There are two main types of esophageal cancer: 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 drinking too much alcohol.
Adenocarcinoma is the more common type of esophageal cancer. Having Barrett esophagus increases the risk of this type of cancer. Acid reflux disease (gastroesophageal reflux disease, or GERD) can develop into Barrett esophagus. Other risk factors include smoking, being male, or being obese.
