If there is blood in nasal mucus every day, it is not necessarily nasopharyngeal cancer, but it can not be excluded, so it is better for the patient to go to the hospital to complete nasopharyngoscopy first, to make clear the specific situation of the patient’s nasal cavity and nasopharynx, and if the mucous membrane is relatively smooth and there is no new organism formation, the patient can be assured. The main symptom of nasopharyngeal cancer in clinic is blood in inhaled nasal mucus, which is usually found in the late stage, and if there is blood in the patient’s nasal mucus every day, it is mainly considered that the mucous membrane of the nasal cavity is particularly dry, and the mucous membrane inside the nasal cavity is easy to break down and lead to bleeding. In terms of treatment, it is recommended that patients can spray with physiological sea saline, which can effectively play a moisturizing effect. The dryness of the nasal cavity is generally related to the patient’s personal constitution, as well as with the work, living environment and a large number of smoking, drinking or do not like to eat fresh vegetables and fruits have a lot of relations, so we must clarify the cause of the disease after active symptomatic treatment. The patient’s dry nasal cavity, boogers or even blood will be significantly improved.
