A Gallup Poll has found that up to 29% of Americans would consider traveling abroad for medical procedures such as heart bypass surgery, hip or knee replacement, plastic surgery, cancer diagnosis and treatment, or alternative medical care, even though all are routinely done in the United States. "The data suggest the estimated population of 48 million Americans without health insurance are motivated by costs and would be more likely than those with health insurance coverage to consider seeking medical care from alternative sources," according to the study's findings.
