When a teenage girl has breast fibroid, she can choose conservative treatment, and in serious cases, she needs to take surgical treatment. 1. Conservative treatment: If the breast fibroid is smaller than 3cm, conservative treatment can be chosen. Teenage girls should adopt regular work and rest, diet, maintain a good mood, avoid emotional ups and downs, and avoid endocrine disorders. In addition, they need to go to the hospital for regular checkups to clarify the growth of breast fibroid. 2. Surgery: If breast fibroid causes discomfort and is larger than 3cm, surgery is needed to remove the breast fibroid, and usually the prognosis is good after surgery. If a teenage girl has breast fibroid, she should go to the hospital in time to improve the examination and take standardized treatment under the guidance of professional doctors, and should not ignore the symptoms and take it lightly, so as not to lead to adverse consequences.
