"Medical tourism" refers to traveling to another country for medical care. It's estimated that thousands of US residents travel abroad for care each year. Many factors influence the decision to seek medical care overseas. Some people travel for care because treatment is cheaper in another country. Others may be immigrants to the United States who prefer to return to their home country for health care. Still others may travel to receive a procedure or therapy not available in the United States. The most common procedures that people undergo on medical tourism trips include cosmetic surgery, dentistry, and heart surgery (Source: US CDC).
