First, the cause of mammary gland hyperplasia. Breast hyperplasia is caused by the imbalance of estrogen and progesterone in patients, which leads to excessive hyperplasia of breast parenchyma and incomplete involution. Some patients are due to the abnormal quality and quantity of female hormone receptors in the breast parenchymal components, which makes the proliferation degree of each part of the breast uneven.
Second, it can be explained by pathology. Breast hyperplasia mainly occurs around the catheter and in the glandular duct, and also occurs in lobular parenchyma. Occurring around the glandular duct, cysts of different sizes can appear, and the cysts contain yellowish or brownish liquid; Occurring in the glandular duct, it can be manifested as papillary hyperplasia in different degrees, accompanied by cystic dilatation of mammary duct; In lobular parenchyma, the main manifestations are hyperplasia of mammary duct and acinar epithelium. Breast hyperplasia is a lump formed by the proliferation of breast parenchymal cells, which cannot be eliminated by massage and kneading. Therefore, mammary gland hyperplasia occurs, so massage and massage are forbidden, and you should go to the hospital for examination as soon as possible.
