Esophageal Cancer Symptoms, Anatomy And Incidence

Symptoms of esophageal cancer involve a tumor or malignancy in the muscular tube that connects the back of the throat to the stomach. This tube called the esophagus that is about ten to eleven feet long (25-30 cm) and actively contributes to transport food and fluids to the stomach. 

The bottom of the oesophageal tube is equipped with a type of valve structure called the sphincter. This sphincter function is extremely important because it prevents stomach acid leak and damages the tube wall of the esophagus. Long-term chronic damage to esophageal mucosa by acid may contribute to esophageal cancer. After observing such factors of producing cancer, it is recommended by doctors to visit and follow the proper treatment of your problem.

The esophageal wall is made of layers of cells and tissues. Each layer has a separate function and knows which layer is involved in cancer at diagnosis is the key to understanding how cancer is aggressive. The esophagus is not like a water pipe with a single solid layer but instead has multiple layers or coatings.

The innermost layer is constructed from squamous epithelial cells that provide a flat inner coating layer smooth called the mucosal layer. Since the mucosal layer is continuously subjected to friction and scratching by the food through the cells that make up this layer are active in the division to restore the lost or damaged cells. 

The incidence of esophageal cancer is high in several parts of Central Asian countries. In these countries, the incidence is high, probably due to some eating habits, but also some choice of lifestyle, such as smoking. Esophageal cancer is the eighth most common cancer worldwide.
