Throat cancer and pharyngitis are two completely different diseases. Throat cancer is a common malignancy in the field of otolaryngology, whereas pharyngitis is caused by long-term chronic inflammation irritating the mucous membrane in the throat area, leading to symptoms such as the sensation of a foreign body in the throat, as well as dryness, itchiness, and pain in the throat. For patients with throat cancer and pharyngitis, diagnosis can be confirmed through the use of a laryngoscope, a nasopharyngoscope, and a CT scan of the neck with contrast enhancement. For patients with throat cancer, the primary treatment method is surgical removal of the tumor tissue. For patients with pharyngitis, the focus is on care. In daily life, it is advisable to avoid consuming spicy, irritating foods and cold drinks, while it is also important to eat more vegetables and fruits to protect the mucous membrane of the throat and to conserve the voice.
