There are usually three price structures; the price to a private healthcare provider, the price to a self-funder and the price to the NHS when they have to resort to a private facility due to waiting lists or whatever. So while the cost to your insurer was massive, it would probably have been significantly less if you were digging into your own savings. That was how it worked with John’s RP (self funded) and my own treatment (obvs not for PCa!) and when we got a quote for the RT to be done privately, it was nowhere near £27,000 although we were lucky to get back into the NHS system and didn’t need to pay in the end.
