They can spread to other parts of the body, making them extremely destructive. A vast number of oral cancers start in the flat cells. These cells are called squamous cells and are found in the tissues that make up the surface of the skin, the channels of the digestive and respiratory tracts, and the covering of the body's hollow organs. These cancers are called squamous cell carcinomas. By fleeing from the
