They secrete oils that help lubricate and protect the nipple and areola. They are harmless and do not need treatment. 2. Blocked Pores or Skin Infections These white bumps could be blocked pores, pimples, or minor infections. If there’s redness, pain, swelling, or pus, it might be an infection and should be checked by a doctor. 3. Warts or HPV In rare cases, white bumps could be caused by human papillomavirus (HPV), which causes skin warts. Only a doctor can diagnose this accurately. Recommendation: If this is happening on your body or someone else’s, it’s very important to see a dermatologist or medical professional. Only a doctor can give a correct diagnosis and treatment plan.
