Esophagus is explained to be a muscular tube that is hollow and which moves liquid and food from throat into the belly. The esophagus’s wall is normally produced of a variety of tissue layers such as muscle mass, connective tissue and mucous membrane. Ordinarily esophageal cancer commences in the esophagus’s internal lining and spreads to other layers in the outward way when it progresses.
