When patients have symptoms such as unexplained blood in the snot, unilateral nasal congestion, tinnitus, occlusion of ear, hearing loss, headache, diplopia or enlarged lymph nodes in the upper and deep cervical region, they should be alerted to nasopharyngeal carcinoma. 1. Bleeding: when there is blood in nasal mucus, it is usually blood at the beginning, and then it will turn into pus and blood gradually. Early symptoms seldom have nosebleed, but blood in sputum or blood when inhaling the nasal cavity. 2. Ear discomfort: when patients suffer from nasopharyngeal carcinoma, it will block the pharyngeal opening of Eustachian tube, which will cause tinnitus, and some patients will also suffer from occlusion of the ear on the same side and hearing loss. 3. Nasal congestion: when the tumor enlarges and blocks the posterior nostril, it will cause the symptom of nasal congestion, which is unilateral at first and then can develop into bilateral nasal congestion. 4. Ptosis: when the tumor destroys the bone at the base of the skull or invades through the rupture hole and the internal carotid artery canal, causing damage to the cerebral nerves, symptoms such as ptosis will appear. 5. Swelling of lymph nodes in neck: when patients have nasopharyngeal cancer, painless lumps will appear in lymph nodes. With the progress of disease, lymph nodes in neck can be progressively enlarged, hard and poorly movable, which are mostly unilateral at the beginning, and can be developed into bilateral later. Nasopharyngeal cancer may appear cervical lymph node metastasis in early stage, thus it is often easy to be misdiagnosed as lymph node tuberculosis, Hodgkin’s lymphoma and so on. When patients have the above symptoms, they should go to the hospital for consultation in time, and improve the examination to clarify the cause of the disease under the guidance of doctors.
