Mammary hyperplasia, also known as mastopathy, can develop in both men and women, and is most common in women, and is one of the most common diseases in women, mostly seen in women aged 30 to 50. The etiology and pathology of mammary gland hyperplasia: The etiology and pathogenesis of this disease is not well understood, but is now mostly thought to be related to endocrine disorders and mental and emotional factors. Pathology: mainly benign hyperplasia of the interstitial mammary glands, hyperplasia can occur around the ducts and can be accompanied by the formation of cysts of various sizes; it can also occur in the ducts and manifest as papillary hyperplasia of the epithelium with cystic expansion of the milk ducts. Symptoms of mammary gland hyperplasia: 1, breast pain: unilateral or bilateral breast pain or tenderness, the course of the disease varies from a few days to several years, most patients have the characteristics of cyclical pain, manifested as pain before menstruation or aggravated, after menstruation to reduce or disappear. 2, breast lumps: often multiple, unilateral or bilateral, often cyclical with menstruation, lumps increase before menstruation, lumps decrease after menstruation. Signs of mammary gland hyperplasia: multiple lumps can be palpated, irregular, nodular or granular, of different sizes, with poorly defined boundaries with surrounding tissues, mostly with tenderness, without adhesions to skin and deep tissues, and without enlargement of axillary lymph nodes. However, it should be noted that some patients may be accompanied by breast cancer and a few patients (about 1 to 3%) may have undergone malignant changes. Therefore, patients with suspicion should be observed and reviewed regularly, usually once every three to six months. If necessary, surgical excision or puncture biopsy should be performed. Treatment of mammary gland hyperplasia: Generally speaking, when the symptoms of mammary gland hyperplasia are mild, with only slight premenstrual breast swelling and pain, scattered small granular nodules in the breast, no obvious lumps, and their condition does not affect daily work and life, the breast can be held up by a bra to relieve the symptoms without medication, only for regular review; if there are no obvious changes, you can go to a breast specialist once every six months to a year for examination. When the symptoms are serious and affect work or life, and/or there are multiple lumps in the breast, different treatments should be given to each case. Commonly used treatments such as oral Chinese medicine and anti-estrogen drugs can relieve symptoms. If necessary, surgical biopsy is required. Follow-up observation of patients: Once a lump with rapid growth or hardening texture is found within a short period of time, the possibility of cancer should be highly suspected, and if necessary, surgical biopsy or simple excision of the affected breast should be performed. Prevention of mammary gland hyperplasia: 1, maintain optimism, cheerfulness, emotional stability, less anger, regular life, work and rest. 2, healthy food, balanced diet, appropriate control of fatty food intake. 3, timely treatment of menstrual disorders and other gynecological disorders. Avoid abortion and induction of labor; strive to breastfeed after delivery, which is good for the health of both the child and the mother. 4. Monthly self-examination and regular review at the hospital.
