There is no such concept as breast unblocking in medicine. The so-called breast unblocking in beauty salons is through vigorous, regular squeezing and massage of the breasts to promote the discharge of “toxins” in the breasts, to promote “lymphatic drainage” and so on. But for breast enlargement, benign breast tumor or milk performance, this method has no therapeutic effect, may also cause side effects. In the process of breast dredging, the operator will vigorously squeeze the breasts, and most people will experience significant pain, which will persist even after the dredging. In addition, excessive forceful squeezing of the breast can cause breast damage, engorgement, and even subcutaneous bruising of the breast. If you have a benign or malignant tumor, pressing your breasts will also promote the growth and spread of the tumor. Patients with mastocytosis massage their breasts to make them repeatedly and continuously engorged with blood, which may aggravate the condition, and some patients with mastitis and milk will make the inflammation spread after massaging their breasts. In addition, when beauty salons do breast dredging, they often have to use some drugs, which usually contain hormones and may cause some damage to the body. Some patients who are already suffering from breast disease do not want to undergo surgery and believe in non-therapeutic means such as mastopexy, which may delay the condition and delay the best time for treatment.
