All surgery carries risk, and you should be fully aware of the medical risks associated with this procedure before you consent to surgery. Your surgeon will discuss these risks with you during your consultation, and you are encouraged to ask questions if there is anything you do not understand

You will be required to sign a consent form before surgery stating that you have been informed of the risks involved; that you understand those risks; and that you accept those risks. This is standard hospital protocol and surgery will not be performed if you do not sign

It is your obligation to inform your surgeon of key medical information that may influence the outcome of your surgery or may increase the level of risk. These include medications you are taking, history of disease, medical complications, etc.
Risks and risk rates vary from patient to patient depending on a range of factors. No two people are alike. The risks listed below are possible risks associated with this type of surgery and are mentioned regardless of how remote the possibility:
Shifting or imprecise positioning of implant, or infection around it, requiring a second operation or removal.
Excess tightening and hardening of scar tissue around an artificial implant ("capsular contracture"), causing unnatural shape.
