Head and neck cancer consists of tumors of mouth, throat, voice box (Larynx) and the associated structures such as sinuses, salivary and thyroid gland. It is now clearly established that multimodality treatment with surgery, radiation therapy and chemotherapy alone or in various combinations offer the best chance to cure the disease and to improve the quality of life of patients. Because of the involvement of multiple specialties, the treatment decision and monitoring is best carried out through a multidisciplinary head and neck oncology team, rather than by a single physician or a specialty.
