Oral Cavity: Oral cavity cancer, also called oral cancer or mouth cancer, starts in the mouth. It includes the lips, the cheeks, or the front of the tongue. These tumors can involve the mandible and can affect speech and swallowing.
Oropharynx: Oropharyngeal cancer starts in the middle part of the throat. It includes the base of the tongue, soft palate and tonsils. There are many types of cancer of the oropharynx. Most of these cancers are squamous cell carcinomas. The incidence of these tumors is on the rise.
Nasal Cavity and Paranasal Sinuses: Nasal cavity cancers start inside the nose. Paranasal sinus cancers most often start in the maxillary sinuses in the cheeks and below the eyes on either side of the nose. These tumors can also involve the skull base, the orbit, or nerves that given sensation to the face. A number of different cancers originate in this area, including squamous cell carcinoma, olfactory neuroblastoma, or adenoid cystic carcinoma.
Larynx: Laryngeal cancer begins in the larynx, or voice box. Almost all laryngeal cancers develop from squamous cells, which are thin, flat cells in the inner lining of the tissue. A tumor in this area can affect the voice, swallowing, or the airway.
