There are risks to plastic surgery, which are the same risks that you'll find if you undergo any surgery. There's a risk of a reaction to the anesthesia, as well as a chance for infection or other post-surgery complications. Finally, you can be unhappy with the way that your surgery has turned out after healing; you may expect some results that are impossible due to your underlying structure, or your surgeon may not be able to complete the dramatic transformation you're hoping for.
