I don’t think you’d be able to give enough personal information, in this open forum, about your wife for anyone who knows the NHS to explain this. Your mention of politics is intriguing…
Also I am unsure whether you mean by Dr 1, the surgeon who sought a second opinion and whether that opinion was at a different hospital. Are they part of a multi-disciplinary team?
I’d love to know more to be able to understand and possibly interpret this for you, but I don’t think here is the place.
You don’t usually get Surgeons warning each other off. Possibilities might include that Dr 1 had not given Dr 2 all the information, or had realised something which made the decision to proceed to surgery less sensible. Or ???
However I can understand why you are pissed off. I would think your best chance of an explanation would come from Dr 2
Sorry not to be more use.
