Nothing new - Europeans are doing this all the time - one of their favorite vacation/surgery destinations is Thailand; next you will see China become a favorite for blood analysis, radiologist readings, - the whole nine yards.
Last November I needed an new bridge and my local dentist
quoted $9600. I flew to Budapest, and got it done for
$2000 including airfare, lodging for 10 days, meals and
incidental expenses. Like a mini vacation.
