When it comes to head and neck tumors, it may be relatively new to most people. It is a way to classify tumors according to body parts, which has been adopted by more and more oncology specialty hospitals and non-specialty hospitals. That is to say, tumors are divided into head and neck tumors, chest tumors, abdominal tumors, limb tumors, etc., instead of classifying them by various systems. “Head” means head and “neck” means neck, which is commonly known as “neck”. Then, what are the head and neck tumors? It should include neck tumor, ENT tumor and oral and maxillofacial tumor. Neck tumors belong to general surgery in general hospitals, and the more common ones are thyroid tumors; ENT tumors include laryngeal cancer, paranasal sinus cancer, etc.; oral and maxillofacial tumors include various oral cancers, such as tongue cancer, gum cancer, cheek cancer, etc. Therefore, tumors of head and neck are the most common among all tumors in the body in terms of primary sites and pathological types. Meanwhile, the important organs of head and neck are concentrated, the anatomical relationship is complex, and the treatment methods are different. It simultaneously involves multidisciplinary medical fields such as head and neck tumor surgery, medical oncology, radiation therapy, nutritional language therapy, social work, nursing and rehabilitation. And some parts of the tumor need to have multidisciplinary collaborative and comprehensive treatment in order to effectively improve the treatment effect.
