Mammary gland hyperplasia is a common and frequent disease in women. It is a kind of proliferative lesion that is neither inflammation nor tumor with lumps and swelling pain in the breast as the main clinical manifestation, and it is a general term for a group of diseases with basic pathological changes of proliferation of epithelial cells and connective tissue in the breast, alveoli and ducts. It is generally believed that mastoproliferative disease is caused by the imbalance of endocrine hormone level and the disorder of sex hormone metabolism, which leads to the excessive secretion of estrogen in the body, resulting in physiological hyperplasia and incomplete restoration of the breast gland, and in addition, the abnormal function of the liver to inactivate estrogen, so that excessive estrogen stimulates the breast tissue adversely and causes hyperplastic lesions. Mammary gland hyperplasia can be divided into breast pain, lumps, lobular hyperplasia, fibroadenosis, advanced fibrosis, and breast cancer according to the development of its pathological form. Its clinical manifestations are mainly: breast pain, breast lumps, nipple overflow, menstrual disorders and changes in line pattern. Mammary gland hyperplasia was first described in Chinese medicine in the Han Dynasty in Hua Tuo’s “Zhong Zang Jing” as breast fetish, in the Ming Dynasty in Wu Zhi Wang’s “Ji Yin Gang Mu” as breast rock, and in the Qing Dynasty in Gu Shicheng’s “Breast Gang”. The Chinese medical mechanism of mammary gland hyperplasia has three main points: 1, due to the seven internal injuries, depression, depression long injury to the spleen or irritability and anger can lead to liver qi stagnation, loss of drainage. The breast is the main liver meridian, liver qi is depressed in the stagnant, breast meridian obstruction, not pass is pain, there is anger injury to the liver, thinking about the injury to the spleen, spleen loss of health, phlegm turbidity, resulting in liver and spleen injuries, phlegm and gas, the formation of breast hyperplasia. 2. Disorders of flushing (referring to female patients), patients with irregular menstruation and deficiencies of both qi and blood cause stagnation of qi and blood, which accumulate in the breast and uterus, resulting in breast pain in the upper breast and lumps in the breast, turning into mammary gland hyperplasia, and menstrual disorders in the lower breast. 3, due to excessive intercourse caused by liver deficiency and blood dryness, kidney deficiency and essence deficit, the qi veins can not go up, the liver meridian breast complex is not to honor and nourish, turned into mammary hyperplasia. Chinese medicine believes that breast diseases are mostly caused by emotional discomfort and liver qi stagnation, which is painful when it does not pass. Therefore, in the treatment of this disease, the main treatment should be to dredge the liver and liver, regulate qi and activate blood.
