Head and Neck Cancer
What is head and neck cancer?
Head and neck cancers are a group of cancers that form in the tissues of the upper aerodigestive tract (lips, tongue, mouth, throat and larynx or voice box) or the sinuses and nasal cavity. Most head and neck cancers originate from the squamous cells that make up the lining of these tracts and cavities and are therefore called squamous cell carcinomas.1
