White granular stuff on the nipples is mainly divided into two possibilities: physiological and pathological factors. The physiological reason is that the nipple and the surrounding skin are rich in sebaceous glands and other secretory glands, and when the secretions increase and are not cleaned up in time, white granular material can crystallize on the surface of the nipple. The pathological factor refers to septic infections of the nipples, which can be treated by local disinfection with iodophor, application of roxithromycin ointment and, if necessary, intravenous penicillin anti-infection treatment in the early stages of infection, while if an abscess forms in the breast or sebaceous gland, it is necessary to go to a regular hospital for general surgery or breast surgery to perform an incision and drainage of the breast abscess. All in all, if white granules appear on the nipples, the nature should be clarified and reasonable treatment under the guidance of a specialist can usually be cured.
