Breast hyperplasia, also known as lobular hyperplasia, includes clinically observed conditions such as cystic mammary disease, chronic mammary disease, chronic cystic mastitis, mammary dysplasia, breast cysts, and cystic hyperplasia of the breast. It is a common benign condition of the breast. It is commonly seen in middle-aged women and is mostly related to hormonal imbalances in the body. It is not an inflammation or a tumor, but a physiological response of the body to hormonal imbalance, representing a disorder of the normal structure of the breast. To examine breast hyperplasia, one should of course visit the breast department at a formal hospital for a consultation! If a small hospital does not have a breast surgery department, a consultation can be made in gynecology.
