It is a common benign disease that occurs more often in middle-aged female patients. Not only is there an obvious hard lump, but there is also an obvious change of bloody nipple overflow. Further color ultrasound examination of the breast should be selected. Although it is a benign disease, it should be surgically removed in a timely manner because it has the potential to become malignant and is also affected by hormone levels in the body. The lesion can be removed under local anesthesia or epidural anesthesia, and postoperative pathological histological examination is routinely performed.
