Nasopharyngitis and nasopharyngeal carcinoma have fundamental differences. Nasopharyngitis is an inflammatory disease, while nasopharyngeal carcinoma is a malignant tumor disease. Clinically, nasopharyngitis mainly presents with increased secretions in the nasopharyngeal area, sometimes with a slight amount of bloody secretions, but this is extremely rare. On the other hand, nasopharyngeal carcinoma primarily shows symptoms such as the proliferation of malignant tumor tissues in the nasopharynx, enlargement of the lymph nodes in the neck, headaches, and ear stuffiness. In terms of treatment, nasopharyngitis is primarily treated with medications, such as traditional Chinese medicines, nasal sprays, and nasal corticosteroids; whereas nasopharyngeal carcinoma is primarily treated with radiotherapy combined with chemotherapy, which is currently the common sandwich therapy. Overall, there are fundamental differences between the two.
