In general there is no necessary connection between taking red gold knot-eliminating capsules, breast enlargement and the appearance of pus, the appearance of pus may be caused by breast trauma, bacterial infection, tumor lesions and other reasons. 1. Breast trauma: after the breast is impacted by trauma, the local tissues are prone to inflammatory masses or internal hematomas, which may lead to suppurative changes in severe cases. 2. Bacterial infection: If the patient suffers from an infectious disease such as mastitis, bacteria and viruses invade the breast tissue when there is a breach in the nipple or breast, which may lead to suppurative changes in the breast. 3. Tumor lesions: patients with breast tumors, if the tumor is large, lesions may occur, the lesions of the tissue may appear ischemia, necrosis, and ultimately the formation of breast abscesses. Although red gold elimination capsule is the treatment of breast lobular hyperplasia, but it can not avoid the emergence of other pathological conditions in the breast, it is recommended that patients go to the hospital in time to do further examination, to clarify the cause of the disease as soon as possible to take treatment.
