Breast hyperplasia: mainly caused by endocrine disorders, manifested as nodules or lumps in the breast, breast pain, nipple discharge and other symptoms. 2. Montgomery’s nodule: it is formed because there is a bulge at the opening of Montgomery’s gland ducts, which is granular, the size of a grain of rice, gray or brownish-red in color, usually in the peripheral part of the areola, capable of secreting oil to protect the nipple as well as the skin at the areola, which is a kind of normal physiological structure. 3. Skin inflammation: If the patient’s breasts are not cleaned properly, it may lead to local skin infection by fungi or bacteria, resulting in skin inflammation, skin patches, pimples and so on.
