Head and neck tumors in children are easily overlooked, missed and misdiagnosed. So, what symptoms should be suspected as head and neck tumors on weekdays? According to the cavity characteristics of eye, ear, nose and throat structure, when the tumor grows in the cavity at the early stage, there is no symptom, for this reason, when we have annual physical examination, don’t forget to check the five senses of head and neck carefully. When the tumor breaks down in the process of growth, the blood vessels of the tissues rupture, and the symptoms of blood in nasal mucus and blood in sputum will appear. Generally speaking, nasopharyngeal cancer, nasal sinus cancer, laryngeal cancer, tonsil cancer, hypopharyngeal cancer, and lymphoma in the nasopharyngeal and throat area will have blood in snot and sputum as symptoms. Chronic suppurative otitis media that remains unresolved for years, with blood in the ear secretion and ear pain at the same time, one should be alert to the possibility of middle ear cancer; pain in the throat and foreign body sensation in the throat may be laryngeal or pharyngeal cancer; hoarseness with continuous aggravation of the voice and long term smokers should also be alert to laryngeal cancer. As for eye tumors, if the pupil shows obvious yellow light reflex, it may be retinoblastoma in attack; if you can see things distorted, smaller, and dark spots in the center, you should suspect whether you are suffering from choroidal melanoma. It should be reminded that nasopharyngeal cancer is the most common tumor in the head and neck. As nasopharyngeal cancer is very prone to lymph node metastasis, painless lumps in the neck become a major reason for patients’ initial consultation. If painless lymph nodes in the neck are touched in daily life, patients should consult the doctor in time to clarify whether it is a signal of inflammation, tuberculosis, lymphoma or tumor metastasis.
