Mr. Li in Hangzhou, his ears were like a faucet installed inside, there was always a dripping sound of running water, and Mr. Li was distracted by this tinnitus sound. After almost a month, the sound in his ears was getting louder and louder, becoming like driving a train. His hearing was also decreasing, and he often had trouble hearing his colleagues and family members. An examination of Mr. Li revealed an abnormality in his nasopharynx. After pathological biopsy, the real culprit of the patient’s tinnitus – nasopharyngeal cancer – was discovered. The relationship between nasopharyngeal cancer and tinnitus is quite close. Statistics show that more than 65% of patients with nasopharyngeal cancer have tinnitus symptoms. The sound in patients’ ears varies from person to person, some are like cicadas and insects, some are like wind and machine roar, etc., and the severity varies. Why do patients with nasopharyngeal cancer have tinnitus symptoms? Nasopharyngeal cancer often occurs near the opening of the eustachian tube, blocking the opening of the eustachian tube in the side wall of the nasopharynx. Therefore, patients often experience tinnitus on the sick side, which gradually worsens and is accompanied by hearing loss. Nasopharyngeal cancer can be detected early. A blood test with antibodies to the EBV can help detect early nasopharyngeal cancer. If there are no antibodies, it is generally safe to do so within 5 years.
