Dear Mermer, Front and side view pictures would have been very helpful. Breasts asymmetry is very common (breasts are sisters and not twins) , but not to the degree that you describe. Polland syndrome comes to mind. I am sure that your situation is quite frustrating, especially, for living with it for so many years. The good news is that the breasts can be made more symmetrical , either by augmentation or reduction , according to your desire. You have to realize, that not all results are the same, because experience, skills and aesthetic eye are critical for good outcome. So, do your due diligence carefully and choose your surgeon wisely, to avoid bad result that will require corrective surgery. Always, consult with experienced board certified plastic surgeons who operate in accredited surgery center for your safety. Most importantly, check the before and after pictures in the photo gallery, to make sure that they are numerous, consistent and attractive. Best of luck, Dr Widder
