The Rate of Esophageal Cancer Continues to Increase in Western Countries Due to the Epidemic of Gastro-Esophageal Reflux Disease.
The esophagus links the mouth to the stomach, forming an important part of the body’s digestive system. Although esophageal cancers make up a small percentage of all cancers diagnosed annually, one form, esophageal adenocarcinoma, is increasing at a faster annual rate than any other cancer. It is diagnosed most frequently in an advanced state.
It is not clear what causes esophageal cancer. It is known that esophageal cancer occurs when cells in your esophagus develop errors (mutations) in their DNA. The errors make cells grow and divide out of control. The accumulating abnormal cells form a tumor in the esophagus that can grow to invade nearby structures and spread to other parts of the body.
