Usually performed as an outpatient procedure, breast reduction surgery generally lasts 3-4 hours or more, under general anesthesia or a local anesthetic. Risks of the procedure can include infection, fluid accumulation, rippling, baggy, or injured skin, asymmetry, pigmentation changes (which may become permanent if exposed to sun), excessive scarring, and changes in sensation. When considering breast reduction, it's important to discuss the risks and benefits with your plastic surgeon to decide whether the procedure is right for you. Some breast reduction procedures are also covered by health insurance policies.
