Beware of 6 common symptoms of nasopharyngeal cancer, as follows: 1. Prolonged nasal congestion When the nasopharyngeal tumor is large and blocks the back nostril, the patient often feels nasal congestion. However, the nasopharyngeal congestion caused by nasopharyngeal cancer often worsens progressively and does not come and go like a cold.
2. Tinnitus This is not necessarily inflammation, but needs to be investigated. When the tumor blocks the opening of the eustachian tube, it causes buzzing in the ear in the early stage and continues to cause hearing loss, which is easily misdiagnosed as otitis media. Hearing loss will also occur later after routine treatment of otitis media.
3. Facial numbness and retesting The tumor grows into the skull and compresses the nerve causing facial numbness and difficulty in chewing. Patients often have the sensation of facial pain allergy or ants crawling on the face. When the tumor compresses the motoneurotic, talipes, and abducens nerves, patients will have double vision when looking in the lateral direction.
4. Painless growth of cervical lymph nodes 60%-90% of patients with nasopharyngeal carcinoma have swollen lymph nodes at the first treatment. The lumps are located in the upper neck and grow painlessly and gradually, single or several, with hard texture. When encountering such a situation, many people would mistake it for lymph node inflammation, but the effect of lymph node swelling after anti-inflammatory treatment is often not obvious.
5. Early morning retractable blood snot Deep inhalation and spitting with blood. Especially in the morning after waking up, the sputum often has blood in it.
6. Deflection of tongue extension In the advanced stage of nasopharyngeal cancer, cancer cells can invade the sublingual nerve, resulting in the loss of innervation of tongue muscle.
