Head and neck cancer is a term used to describe cancers that arise from the cells that line the mouth, tongue, throat, larynx, nose, and sinuses. These cancers are usually squamous cell carcinomas.
Occasionally, cancers may start from the salivary glands of the head and neck area. These are called salivary carcinomas and these cancers are usually adenocarcinomas. These may include adenoid cystic carcinoma and mucoepidermoid carcinoma.
