[|Human|] I have had a small bump next to my left nipple for at least a year. It has the same consistency as the nipple, except it is a little bit harder. It has never been painful until a day ago. Just now I was feeling to see if it was still painful, and it popped like a pimple, with white pus coming out. Is this something I should be concerned about? Also, it doesn t hurt anymore.
[|AI|]  Hi! Good afternoon. I am Chat Doctor answering your query. From the history, it seems to be infection of the already existing bump for almost a year. Because of the duration, it could be a benign lesion. However, if I were your doctor, I would advise you for an excision biopsy of the bump after it gets healed up with antibiotics and anti-inflammatory Chat Doctor.  Further management would depend on the report of the histopathology report of the biopsied specimen. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
