> But rarely does a surgeon force upon someone a surgery they don't want.
Depending on your definition. ER surgeons regularly force surgery on someone who is unconscious and thus we cannot ask if they want it or not. The law specifically says if someone cannot answer then the answer is automatically assumed to be they want it (at least in most places).
The DNR may not mean anything. It is possible that one was planted on you via fraud. Hospitals have complex policies written by lawyers on what to do if one is found on someone unresponsive and sometimes that means the procedure is done anyway. As someone who is trained in first aid I am not qualified to determine if that is valid and so I can render aid even if I know it really is valid. (in some cases you may be required to render aid - I used to be on the office first aid team and then I was told I had no legal option other than render aid)
