Patients with nasal cavity erosion have a certain possibility of cancer, but only if the erosion occurs repeatedly. If it only happens once in a while, the chance of cancer is very low. It is most likely due to always picking the nose or inflammation of the nasal mucosa, and often the symptomatic treatment will bring significant improvement. Clinically, it is commonly used to rehabilitate the new solution, also can apply recombinant bovine basic fibroblast growth factor gel, which can reduce the degree of mucosal erosion while anti-inflammatory and anti-swelling, and can also apply gentamycin ointment appropriately. However, if the patient has recurrent erosion in a restricted location in the nasal cavity, pathology should be taken to determine whether cancer has occurred and further treatment should be given if necessary.
