Esophageal cancer is a rare form of cancer, but its numbers are on the rise around the world (Staff, Mayo Clinic 1). This disease occurs when malignant or cancerous cells form in the tissues of the esophageal lining of the body’s gastrointestinal tract. The esophagus is responsible for moving swallowed food and liquids from the mouth into the stomach for digestion. It consists of several tissue layers, including the mucous membrane, muscle, and connective tissues.
