Cancer of the Esophagus
CancerIndex Home - Guide to Internet Resources for Cancer Home> Cancer Types> Esophageal Cancer

The esophagus (UK spelling: oesophagus) is a long hollow muscular tube which connects the throat to the stomach. Esophageal cancer is a disease where malignant (cancerous) cells arise in the tissues of the esophagus. The most common symptom is difficulty in swallowing. It can also be associated with weight loss and sometimes pain or discomfort behind the breast bone or in the back - these symptoms should be checked by a doctor but not are sure signs of cancer. There are two main types of esophageal cancer (depending on how the cells appear under the microscope); approximately half are classed as "squamous cell carcinomas" and half as "adenocarcinomas". People with frequent gastric reflux leading to Barrett's Esophagus have an increased risk of developing esophageal cancer.

Barrett's Esophagus, Reflux and Risk of Esophageal Cancer

Gastric reflux is where stomach acids frequently travel back up into the esophagus. This causes irritation to the cells lining the esophagus. Over time this may develop into Barrett's esophagus, where the cells in the irritated part of the esophagus begin to resemble the cells that line the stomach - changing from normal stratified squamous epithelium to metaplastic columnar epithelium. Gastric reflux and Barrett's esophagus are risk factors for esophageal adenocarcinoma.
