Cancer,
esophagus: Cancer of the swallowing tube that passes from the throat to
the stomach. The risk of cancer of the esophagus is increased by
long-term irritation of the esophagus, such as with smoking, heavy
alcohol intake, and Barrett’s esophagitis. Cancer of the esophagus can
cause difficulty and pain with swallowing solid food. Diagnosis of
esophageal cancer can be made by barium x-ray of the esophagus, and
confirmed by endoscopy with biopsy of the cancer tissue.
