"Even if you dot all your i's and cross all your t's and you go to the best surgeons in the world, there still are risks," says Dr. Haworth, adding, "But when plastic surgery is performed by fully certified board plastic surgeons in qualified surgical centers, the risks are far, far, far more minimized."
