Most commonly, however, "head and neck cancer" refers to epithelial carcinomas, squamous cell cancers, and their variant histologic subtypes that arise from the mucosal surfaces of the upper aerodigestive tract and constitute over 85% of the cancers encountered in this region. Those caring for patients with head and neck neoplasms must be conversant with the variable natural histories and approaches to treatment for the many different malignant tumors that arise within this region.
