Nosebleeds in a 12-year-old girl may be caused by factors such as hemangioma or local inflammation. A hemangioma located on the nasal septum or inferior turbinate can lead to nasal bleeding. Unexplained nosebleeds in a 12-year-old girl are usually due to local inflammation of the nasal mucosa and blood vessels. Minor, recurrent, and frequent episodes of epistaxis typically improve after local treatment.
