Breast lobular hyperplasia and breast hyperplasia are the same; they are both referred to as cystic hyperplasia of the breast, a common breast disease seen in women aged 25-50. Clinically, 50% of women exhibit changes associated with cystic breast hyperplasia. Its main characteristics are the proliferation of breast tissue components, manifesting as abnormalities in structure, quantity, and histology. In addition to the benign proliferation of breast fibrous tissue and epithelium accompanied by cyst formation, it may also coexist with the formation of fibroadenomas. However, the absolute risk of developing into breast cancer is extremely low, hence it is also termed cystic breast hyperplasia or breast dysplasia.
