A breast surgeon is one who will be trained in operating on breasts. There are several reasons a breast surgeon may be required. A breast surgeon may be needed to do a biopsy to determine if the tumor is cancerous. They remove tumors as well. A speciality in cosmetic surgery for a breast surgeon would be augmentation.
Some women do not require breast augmentation, but rather feel they need it. In either case a breast surgeon can enlarge or reduce a woman’s breasts. Like many doctors these surgeons have to study for years in general medicine and work their way up to the speciality of breast surgery. They have a choice in what kinds of procedures they wish to do depending on where they work.
