Generally, it is considered related to breast hyperplasia. We can diagnose it through breast ultrasound or mammography. Currently, breast hyperplasia is mainly thought to be related to an increase in estrogen levels caused by endocrine disorders. The external environment in which people live, work and living conditions, interpersonal relationships, and various other pressures causing neuro-psychological factors, can change the internal environment of the body, thereby affecting the function of the endocrine system, and then causing the secretion of one or several hormones to be abnormal. During the menstrual cycle, the receptors in the breast undergo cyclical changes due to changes in hormone levels. When the balance of hormone levels in the body is disrupted, with an increase in estrogen levels and a decrease in progesterone secretion, it may cause incomplete regression after breast hyperplasia, leading to the proliferation of breast tissue. Therefore, the functional state of the ovaries and the presence of disorders play a very important role in the development of the disease.
