We have patients in the UK from all over the world because they want a particular treatment or doctor not available in their country.
It does not necessarily mean it is not available in their country but not the treatment they want or can afford.

The answer to your comment is "Yes and no." PRIVATE British medicine is often excellent. The SOCIALIZED NHS is less than adequate. In fact it is the among the worst in Europe.
