    There are five main types of head and neck cancer, which are all named according to the part of the body where they develop: laryngeal (voice box), nasal cavity and sinus, nasopharyngeal (air passage way behind the nose), oral (mouth), and salivary gland cancers. Most of these cancers are squamous cell carcinomas (SCCs), meaning they begin in the flat (squamous) cells that make up the thin surface layer of the structures in the head and neck.
