[|AI|]  Hello, I have studied your case and I think that this can be an enlarged lymph node. It can be due to infection. I would also suggest you to show it to a breast expert, and he may advise you to get needle test or an ultrasound of the breast. It will give us final conclusion if you need any further treatment.  I hope this answer will be useful for you. Let me know if there is any other followup questions. Thanks
