Chronic pharyngitis is generally not cancerous, but before the diagnosis of chronic pharyngitis must be perfected the necessary specialist examination, to exclude the possibility of cancerous lesions and precancerous lesions. Part of the reflux pharyngitis caused by gastroesophageal reflux disease has the tendency to evolve into cancer, so it needs to be actively standardized treatment and regular review. Chronic pharyngitis is a chronic inflammation of the pharyngeal mucosa, submucosa and lymphatic tissue. It is generally a benign lesion, with recurrent nausea, dryness, itching and tingling in the pharynx as the main manifestations. Patients are often associated with poor lifestyle habits and nasal diseases. Chronic pharyngitis generally does not directly develop into cancer, but if patients are stimulated by long-term bad habits, such as smoking, drinking, etc., there is a risk of transforming to tumors, abnormal keratinization and proliferation of mucosa, mucosal atypical hyperplasia, etc., and if it develops for a long time, it may develop into hypopharyngeal cancer. It is recommended that patients with chronic pharyngitis should actively seek medical treatment, and after systematic examination and clear diagnosis, follow the doctor’s instructions to standardize the treatment, so as to avoid the transformation of inflammatory diseases to cancer due to the stimulation of risk factors.
