Breast nodules are a type of breast lump that includes benign and malignant lumps. Benign lumps are common in women of childbearing age and resolve on their own after menopause. There are four types: breast pain (premenstrual during adolescence, painful during menstruation, no lump, disappears after menstruation); lobular hyperplasia (20-35 years of age, premenstrual pain with multiple small nodules, resolves after menstruation); fibroadenoma or papilloma (single lump with clear borders, large activity, no pain, adhesions); fibrocystic hyperplasia or sclerosing mastopathy (after 30 years of age, multiple small nodules, in patches, tough, with poorly defined borders. often bilateral, light pressure pain, related to the menstrual cycle) surgical treatment. Breast nodules are structural degenerative lesions and progressive connective tissue growth in the ducts and lobules of the breast tissue, and their pathogenesis is mainly due to endocrine hormonal imbalance. Marriage, diet, the external environment of human existence and genetic factors are the main causes of breast pathogenesis. The symptoms of the disease are mainly characterized by periodic pain in the breast. At first, the pain is diffuse and distending, and the tenderness is obvious in the upper and middle part of the breast, and the pain increases before menstruation every month, and decreases or disappears after menstruation. In severe cases, the pain is persistent before and after menstruation, and sometimes the pain radiates to the axilla, back of the shoulder and upper limbs. The clinical manifestations of breast nodules are often characterized by breast pain and breast lumps, as well as individual nipple overflow, which is mostly cool, colorless and plasma-based. If the overflow is yellow or bloody, the amount may be pathological and should be taken seriously enough to go to the hospital in a timely manner; breast pain is often unstable and can be aggravated before menstruation, and also often aggravated by emotional changes, exertion and weather changes. If the pain is more than 3 months, and the pain affects daily work and life, medication intervention is needed; breast lumps are the main basis for the diagnosis of mastopathy, most of them are multiple, the size of the lumps varies, the texture is hard or hard and tough, the lumps do not adhere to the skin, the surface of the lumps is often not smooth, and there is a granular feeling when touched; some patients with mastopathy also have systemic symptoms such as bitter mouth and swollen ribs, chest tightness, anorexia, menstrual disorders Some patients with breast enlargement also have systemic symptoms such as bitterness and swelling, chest tightness, anorexia and menstrual disorders. Breast palpation: Breast palpation can reveal slightly large breast nodules, benign nodules have clear borders and are movable; mammography: It can clearly show nodular lesions less than 25px in the breast, and can better characterize and locate the lumps. Malignant nodules are mostly round or irregular in shape on mammography, with 70% of the lesions having rough edges or lobes, and subtle calcifications can be seen in some of the lesions or on all sides; color Doppler ultrasound: can show smaller lesions in tissues and organs more clearly, with detectable pericardial echogenicity, mostly low and medium homogeneous echogenicity; and can show blood flow distribution; pathological histology Examination: Nodules can be histologically diagnosed by hollow needle biopsy or excisional biopsy under molybdenum palladium or ultrasound positioning to determine the nature of the nodule. V. Treatment Since mastocytosis is mainly caused by hormonal imbalance, treatment should start with endocrine regulation. At present, the better treatment for breast enlargement is medication, followed by traditional Chinese medicine, whose treatment principles are: (1) De-stressing the liver and regulating the qi. (2) Invigorate blood circulation, remove blood stasis, and unblock breast channels. (3) Softening phlegm and eliminating swelling and nodules. Gua sha treatment: using scraping the corresponding area of the back breast (i.e. the part of the back corresponding to the front breast), first applying scraping oil, then scraping from top to bottom and from inside to outside in turn; acupuncture treatment, cupping treatment, massage treatment. Six, disease prevention In order to detect breast disease in a timely manner, experts advocate that women over the age of 25 must self-examine their breasts every month (the specific method is: stand in front of the mirror after bathing to check, hands crossed, the body do left and right rotation, from the mirror to observe the skin of the bilateral breasts for abnormalities, nipple inversion, and then use the finger belly against the breast to move slowly in a clockwise or counterclockwise direction, do not squeeze and pinch with your hands to avoid the (Do not squeeze with your hand, as this may mistake normal breast tissue for a lump).
