Head and neck cancers include those that occur in the structures of the neck, throat, mouth, nose, and sinuses. The majority of head and neck cancers are caused by the use of tobacco products and alcohol. Head and neck cancer may lead to difficulties with swallowing, breathing, talking, and eating. Head and neck cancer may be treated with radiation therapy, chemotherapy, surgery, or a combination of treatment types. Valley ENT physicians are well trained and experienced in all aspects of diagnosis of diseases of the Head and Neck, which would refer more to the non-sinus and ear part of the specialty. This has to do with anything from mouth lesions, sore throats, hoarseness, swallowing disorders, as well as lumps in the neck for both the adult and pediatric population.
