Esophageal Cancer: About Esophageal Cancer

Esophageal cancer occurs when abnormal cells form in the esophagus, a muscular tube that allows food to pass from the throat into the stomach.

There are two types of esophageal cancer.

  • Squamous cell carcinoma begins in flat cells lining the esophagus. This generally occurs in the upper and middle portions of the esophagus.
  • Adenocarcinoma begins in cells that release mucus and other fluids. This usually affects the lower portion of the esophagus, closest to the stomach.
