I have a white shaped large bump by my nipple incision: is this normal? (photo)

Thank you for your photo. It looks like a superficial suture abcess which can occur in some instances. Due to the size and history of recent implant placement, I reccomend you contacting your plastic surgeon as soon as possible.

Hi and thank you for your question. from your photograph the lump would be consistent with a suture reaction often called a suture abscess which could require a course of antibiotics if the area becomes painful, hot, swollen and red, as well as local anaesthetic aspiration or drainage. See your PS
