1, breast hyperplasia is the most common benign lesions of the female breast, conservative estimates of more than 60% of lesbians to varying degrees. 2, its basic structural changes are breast follicles, ductal epithelial cells tumor-like hyperplasia, cystic expansion of the milk ducts, interstitial fibrous tissue cystic degeneration, resulting in changes in the structure of the mammary glands, the formation of different forms of multiple nodules. 3, the cause of its occurrence, the researchers are mostly believed to be related to the lesbian endocrine microbalance imbalance, inconclusive. 4, often manifested as palpable glandular structure disorder, multiple cystic and solid nodules, combined with pain symptoms. 5, breast hyperplasia is divided into ordinary hyperplasia and atypical hyperplasia. Common breast hyperplasia does not increase the risk of cancer. Atypical hyperplasia ranges from mild to moderate to severe, and the chance of cancer increases significantly. 6. The idea that cystic breast hyperplasia increases the risk of cancer is an outdated and erroneous one. The standardized name of breast hyperplasia in foreign literature is mostly breast fibrocystic disease or breast cystic hyperplasia. 7.Atypical hyperplasia is determined by pathological examination. Physical and imaging examination (ultrasound, molybdenum target, magnetic resonance, etc.) as well as laboratory examination (tumor markers, estrogen, etc.) can not distinguish between ordinary hyperplasia and atypical hyperplasia. 8.The theory of breast cancer: normal – ordinary hyperplasia – atypical hyperplasia – carcinoma in situ – invasive carcinoma, it takes a long decades to develop from normal condition to breast cancer, and only a very few of them have this chance of evolution. 9. Therefore, the vast majority of breast hyperplasia stays in the normal hyperplastic stage and does not increase the risk of cancer. At present, the chances of hyperplasia malignancy are over-exaggerated by quacks and black doctors, with the aim of causing panic among those who visit the doctor, over-medicating, and cheating them out of their money. 10, breast hyperplasia can not be cured, at present, we usually use the domestic taking Chinese medicine, massage, physical therapy, drug injections and other methods can not eradicate breast hyperplasia, and there is no role in preventing the occurrence of breast cancer, so if there is no combination of pain and other symptoms, the treatment is unnecessary, regular check-ups can be. 11. I will discuss the treatment of combined pain in detail in the chapter on breast pain disorders.
