Cancer is a disease that occurs when uncontrolled division of abnormal cells in the body occurs. These cells are referred to as cancerous and malignant. Oral cancer occurs on the lips (usually the lower lip), inside the mouth, salivary glands, tonsils on the back of the throat, esophagus, and the tongue and soft tissues of the mouth. It occurs more frequently in men than women, and is most likely to strike people over 40.
