Peter, here in Canada we have a similar system of medical care(Gov.) , and its certainly not free if you take a look at your high tax load . We have Pre surgery groups/boards where they discuss each case and concur what procedures should be taken. Its usually hospital by hospital , but can be by region too ! I was tipped off by this by a Dr I never met made a comment on my surgery and case back in 2021 . I asked who he was , and they said part of your "review team prior to surgery " . I good there is a few eyes on your case like this . In this case I would question your doctor more and eleven get a second option on your case - never hurts to do so ! This is my opinion not medical advise, et al . God Bless and lets us know how you make out . James on Vancouver Island .
