Breast hyperplasia has a smaller chance of developing into breast cancer, and the occurrence of breast cancer is not necessarily related to breast hyperplasia. Breast hyperplasia is neither a tumor nor an inflammatory disease. From the point of view of histological manifestation, it is a hyperplasia and degenerative change of the breast tissue, which is related to the patient’s endocrine dysfunction. The disease occurs in middle-aged women, adolescents and postmenopausal women, but the proportion is relatively small. Nowadays, 50-70% of professional women in big cities have different degrees of breast hyperplasia. Mammal hyperplasia usually manifests itself in the form of breast pain and breast nodules. The danger lies not only in the disease itself, but also in the psychological pressure on the patient, worrying about whether the breast hyperplasia will develop into breast cancer. There are many types of breast hyperplasia, such as simple lobular hyperplasia, which accounts for the majority of breast hyperplasia. It is important to pay attention to adjusting the mindset, relieving stress, and can be treated with traditional Chinese medicine (TCM), which is effective for most patients. If breast lobular hyperplasia is accompanied by ductal epithelial hyperplasia, patients with severe heterogeneous hyperplasia, this is a pre-cancerous lesion, which should be examined regularly and treated in a timely manner, so as to prevent the disease from occurring in the first place.
