Benign nasal mucosal erosion, even without treatment, can heal spontaneously within 1-2 weeks if the conditions turn out to be good, i.e., the environment turns out to be good. Nasal mucosal erosion caused by poor health or environment can also be effectively relieved within 2 weeks after treatment. In the case of nasal mucosal erosion caused by malignant tumors, the doctor will remind the patient to treat the primary disease promptly. Benign and malignant diseases of the nasal cavity have atypical symptoms and no other different manifestations in the initial stage. When it develops to a certain extent, malignant nasal mucosa diseases such as nasal cancer and sinus cancer will show blood in the nose, persistent blood, or even bleeding. In addition, there is putrid smell, severe nasal congestion, and malignant tumor will also cause ulceration, necrosis, secondary infection, and a large amount of pus nasal manifestation, so to distinguish the difference between benign and malignant, a specialist nasal endoscope is needed to take biopsy for examination.
