Nasopharyngeal cancer usually does not lead to loss of taste, but radiotherapy for nasopharyngeal cancer patients can lead to loss of taste. Common symptoms of nasopharyngeal cancer include bloody nasal mucus, nosebleed, nasal congestion, tinnitus, hearing loss, headache, swollen lymph nodes in the neck, visual impairment, etc. Generally, there is no symptom of loss of taste. However, radiation therapy can lead to loss of taste because it may injure the taste receptors, which can lead to a decrease or loss of taste. In order to understand the condition, patients need blood routine, complete set of tumor markers, nasal endoscopy, head CT, histopathological biopsy and other tests. Nasopharyngeal cancer patients should actively seek medical treatment, do not blindly self-medicate, and follow the standard treatment under the guidance of physician’s interview to reduce the possibility of loss of taste.
