Head and neck cancers originate in the oral cavity, throat (pharynx), voice box, larynx, nose and sinuses, thyroid, parathyroid or pituitary glands. Crucial organs and glands in the head and neck regulate numerous body functions. Structures such as the nose, mouth and throat connect to the vital respiratory and digestive tracts.
