If there is a hard lump in the breast and areola, consider papilloma in the milk duct, which is found in the large milk duct near the nipple pot belly, as the tumor is relatively small most of them do not have conscious symptoms and can be accompanied by bloody nipple overflow, which needs surgery after the ultrasound examination has confirmed the diagnosis. Due to the discharge of breast secretions from the breast ducts, inflammation caused by bacterial infection can also appear as local swelling and pain, which requires oral antibiotic medication and, if necessary, mammography to confirm the diagnosis. Cystic hyperplasia of the breast can also present with pain around the nipple and areola. This pain is mostly cyclical, and the symptoms are significantly relieved after the onset of menstruation. Also, consider localized trauma that causes soft tissue swelling and pain, which can usually be relieved soon. Try to visit a hospital to check the specific situation.
