For a long time, patients of many countries have traveled abroad to seek the expertise and advanced technologies and treatments available in medical center. In the recent past, a phenomenon known as medical tourism has emerged. Medical tourism is characterized by the fact that patients choose to bypass care offered in their own communities and travel to other countries in the world to receive a wide variety of medical services. These include cosmetic, cardiac and orthopaedic surgery, stem cell therapies, but also treatments with experimental or registered gene therapy products.
