Throat cancer is a disease in which cancer cells grow in an abnormal way in the throat. The throat is the hollow tube that runs from behind the nose and mouth, down the neck, to the opening of the esophagus and windpipe.
Cancer occurs when cells in the body (in this case throat cells) divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissues and spread to other parts of the body. A benign tumor usually does not invade or spread.
