Juvenile fibroadenoma although the name is called juvenile, breast fibroma is a common disease in little girls, multiple diseases, generally multiple breast fibromas are routinely treated without surgery. However, it can also be seen in adult females, characterized pathologically by abundant mesenchymal stromal cells, accompanied by epithelial cell hyperplasia, and clinically characterized by faster growth, the tumor can grow to a large size, and some patients’ tumors can even be larger than 7cm or more, and it is generally believed that it occurs with pre-pubertal development or the early stage of development, caused by the stimulation of the local breast tissues by the ovarian sex hormones. Like ordinary fibroadenomas, surgical excision is the only effective treatment, and generally less likely to recur after complete excision. Don’t worry too much about it, and have an ultrasound review once a year. If you are a girl, it is better to wait until you are an adult to have the surgery. Doctor solemnly reminds: because we can’t see the patient, can’t fully understand the condition, the above suggestions are for reference only, specific diagnosis and treatment, please be sure to go to the hospital under the guidance of a doctor!
