often a broad physician who's particularly skilled in operating on the breast. A breast doctor may biopsy a tumor within the breast and, when it is cancerous, eliminate the cyst. A breast physician could also do breast repair after a mastectomy for cancer of the breast. The surgeons who carry out this sort of breast reconstruction are breast oncology surgeons or cosmetic or plastic surgeons. (Surgeons been trained in both these specialities tend to be generally oncoplastic surgeons.) Some breast surgeons in addition do cosmetic breast surgery.
