For smaller bumps, it can often be considered as multiple nipples of the breast, which develop late, so the patient will have small localized bumps, which can be cured by simple surgical excision, and the patient should not worry too much. Secondly, to see if the patient has a combined infection, the patient will have peri-mammary congestion and edema and may need systemic anti-infection treatment. If an abscess is formed, abscess incision and drainage may be required. In addition, supratentorial breast cancer may also present with supratentorial bumps, especially Paget’s disease, which is a localized lesion on the nipple areola.
