If a bump is found in the nostril, the first thing to look at is the area where the bump is growing, and it depends on whether the bump is smooth and the size of the bump. If it is a small bump in the nostril, in the nasal vestibule, it should be considered a papilloma of the nasal vestibule and can be removed by laser or local surgery. If it is in the nasal cavity, against the lateral wall of the nasal cavity, it should be considered to be an enlarged inferior turbinate. Generally, if the enlarged inferior turbinate does not affect the ventilation of the nasal cavity, it can be left untreated; if it affects the ventilation, local excision and bipolar electrocoagulation ablation can be considered. If it is a deeper part of unilateral nasal cavity, and the surface is not very smooth, or even bleeds easily when touched, consider hemangioma, papilloma or other benign and malignant tumors in the nasal cavity, except for hemangioma and hemorrhagic polyps which do not need pathological examination, others can be considered for pathological examination to further clarify the diagnosis and then further treatment.
