Background: I work for the Iran National Health Institute, and I am presently involved in a project that is looking at several aspects of the medical tourism industry.  Our goal is to contribute to the development of a national policy on medical tourism, both inbound and outbound.
Request: Cosmetic surgery is a major focus of medical tourism, and I need to learn more about that topic.  Please write me a report that describes the scale and impact of medical tourism for cosmetic surgery,  I am interested in both benefits and challenges, both for the individuals who travel for this reason and for the destinations to which they travel. I want to take a broad view of cosmetic surgery, including cosmetic dental surgery (e.g., implants).  Please also summarize available statistical information such as the most popular destinations for the most common types of cosmetic surgery, costs, and outcomes.
