Old or damaged cells also may not die like they're supposed to. A tumor is then formed due to the buildup of extra cells. Tumors in the mouth or throat can be malignant, meaning that they are cancer, or benign, meaning that they are not cancer. Malignant tumors may be harmful to life and they can grow back after they are detached. Malignant tumors can also violate and damage neighboring tissues and organs. 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
