Hi there- The rate of risks of all plastic surgery procedures will vary according to your individual health history and lifestyle, how well you follow your surgeon's instructions, and your surgeon, so it's difficult to give you numbers, but I can comfortably tell you that if you find an experienced and Board Certified Plastic Surgeon, and you are healthy and will follow instructions carefully after surgery, you rate of risk should be very low. I am concerned that it may not be very fair to the plastic surgeons you may consult with to discuss risks with you before you have had a consultation, because it is during this thorough and personal visit that you will gain the appropriate perspective on not only the risks of the procedure, but also the benefits of the procedure to you as an individual. This is also the only way that you would be able to understand the risk level for you. But while I don't think you're really getting the information in the way in which it would be most useful to you, your question is a fair one, so here you go: Bleeding, infection, unfavorable scarring, delayed healing, changes or loss of sensation, hematoma or seroma (fluid collecting), skin slough or burn, fat necrosis (firmness or liquefication of the breast tissue due to loss of blood supply), inability to breast feed, difficulty with mammograms, nipple loss, asymmetry, failure to achieve your desired result, and the possible need for revision surgery at your expense.
