Yes, exactly. That's why people from all over the world (including Canuckstan) come to the U.S. for elective surgeries.
Not exactly true. Check out the medical vacation options being offered in the USA. American patients are going on 3/4 month visits to SE Asia, to get complex surgeries done for less than USD 20,000, as compared to more than USD 100,000 out here in the US. Having grown up in a public health care country myself, and having worked for 2 years in an US hospital, IMHO, the quality of care is the same, if not better, in countries outside the USA.
One thing though, the US definitely is heads above other countries in research and the use of advanced techniques and technologies when it comes to health care.
To the OP, reiterating what everyone has been telling, get yourselves thoroughly checked up.
