Surgery abroad carries the same categories of risk as surgery at home (anaesthesia, infection, bleeding, a result that does not match expectation), plus two risks specific to travel: harder aftercare access if a complication appears after you fly home, and no established way to pursue a claim if something goes wrong. The second risk is what a verified, named surgeon and a written claim path exist to close; the first is a risk of the surgery itself, not of doing it abroad.

A number on a website is a claim. A licence checked against the medical register, recorded in your contract, is not. See /verification/.
The same four questions above, inverted, are the fastest way to spot a clinic worth avoiding. See the red-flags guide.
