Patient's question:
NoDoctor's answer:
Hello, breast hyperplasia is generally believed to be related to endocrine disorders and psychological factors. A decrease in progesterone secretion and a relatively increase in estrogen are important causes of this condition. It is primarily a benign hyperplasia of the stroma of the breast. The hyperplasia can occur around the ducts, accompanied by the formation of cysts of varying sizes; it can also occur within the ducts, manifesting as papillary hyperplasia of the epithelium, accompanied by cystic dilation of the ducts. Additionally, there is a type of hyperplasia involving the proliferation of alveolar parenchyma.
