Pharyngeal bursitis is usually not cancerous, pharyngeal bursitis is very different from cancerous diseases in the nasopharynx in terms of etiology, and there is no evidence that pharyngeal bursitis can cause a high incidence of nasopharyngeal cancer. Pharyngeal cystitis is an acute inflammatory disease, which belongs to benign lesions, and it is mainly a benign disease formed after the pharyngeal sac of the nasopharynx of human body is infected by bacteria such as hemolytic streptococcus. The main symptoms are pus flowing from the back of the nose and persistent pain in the occipital region. Nasopharyngeal cancer is a malignant disease formed after normal cells in the body become cancerous due to the combined effect of many carcinogenic factors. Pharyngeal cystitis is usually treated with oral or intravenous antibiotics such as cephalosporin, and then surgical resection of the lesion is given, and the patient can be completely cured. When pharyngeal cystitis occurs, it should be actively followed by the doctor to standardize the treatment.
