Breast evacuation is a program promoted by many beauty salons in the market nowadays, and among the patients in the outpatient clinic, they often ask whether breast evacuation is useful or not. The first thing you need to know is who needs breast sparing. At present, only breastfeeding mastitis caused by milk stagnation needs to be treated through the correct breast milk expulsion techniques and emptying of the milk. At present, there are more breast dredging methods on the market, and claimed to be able to discharge the residual milk, treatment of breast hyperplasia, eliminating breast lumps, etc. In fact, it is relatively unscientific, and even violent breast massage dredging, but also harmful to the breasts. Late breastfeeding milk gradually reduced, a small amount of milk does remain in the mammary glands, a small amount of residual milk will be slowly absorbed by the surrounding tissues, there is no need to be discharged through the massage technique. On the contrary, because of the small amount of residual milk, you must squeeze the breast through a lot of force, it is possible to discharge, but will damage the breast ducts, triggering other diseases. In addition, breast hyperplasia is generally related to endocrine disorders, when the body estrogen and progesterone metabolism is disturbed, the breasts can not be cyclic proliferation of recurrence changes, the formation of breast hyperplasia, the vast majority of physiological phenomena, rather than pathological changes, so do not need special techniques for the evacuation of the treatment. If there is a non-lactating lump in the breast, there is no way to eliminate it through the method of massage and dredging, and vigorous breast dredging will also contribute to the aggravation of the disease. Therefore, when you find a breast lump, you should go to the hospital in time, rather than going to the beauty salon for breast dredging treatment.
