My practice has changed over the years but, in general, I try to avoid operative procedures on the breast if at all possible. If there is an abscess that is superficial and lateral and convincing to be 100% abscess then sure, I'll drain it. If it is central, deep, near areola/nipple then I punt to surgery. If there is any question of cancer, then again...I punt to surgery. Remember, abscess can be 2/2 simple infection or can be secondary to an underlying neoplastic process and sometimes it's very difficult to tell depending on the history and exam of the pt. The last thing you want to be doing with neoplasm is sticking a scalpel or needle through it.
I consider breast to be one of those red flag, highly prone to litigation areas and treat it the same as hand. Cosmesis is huge with women regarding their boobs and therefore I punt these as much as possible unless it's something really simple.
Most "official" sources will tell you to formally consult for sensitive areas such as genitalia, breast, hand, etc.. Here is a snippet from SAEM though I'm sure I could find others. It was the first thing that popped up in the google.
There are few contraindications to this procedure, however, certain situations should prompt consideration of consultation of general or specialty surgical services: large or complex abscesses, those in sensitive areas (face, hand, breast, genitalia) or in regions in close proximity to structures such as blood vessels.
