Can a Plastic Surgeon Perform the Removal of Fibroadenoma?

Dear Amiee1628,
It is NOT a question of ability. The vast majority of Plastic surgeons trained fully in and began their careers as board-certified general surgeons who were skillful in doing all the procedures other general surgeon do. Then - they were additionally trained in Plastic Surgery.
The question before you is SHOULD the breast Augmentation be done at the same time and WHY is a KNOWN fibroadenoma being removed if we already know it is a benign lesion.
Personally, I would not combine the procedures for several reasons. If there is even a small likelihood that your "fibroadenoma" MAY be malignant, why would we want to complicate matters with an implant there? Second, the likelihood of capsular contracture and breast implant infections goes up whenever breast ducts are cut - as in this case. Why would we want to risk that?
I would advise you to separate the procedures and thereby lower the chances of complications.
Good Luck.

Many of the more experienced plastic surgeons came from the era when they also were fully board certified trained in general surgery. They can certainly do your removal. The question is timing.
While it may be convenient to do the two simultaneously, what if on the rare chance the lump was malignant? That would put you into a totally different decision process for treatment and might even require a mastectomy. So you might really want to get this out first and be absolutely sure it is benign.
