Hi Roycool. Welcome to the forum.

This is a tricky one to answer because the way results are given varies by area of the country and from consultant to consultant. This means it's difficult to draw too many conclusions.  All I can say is that it is common practice, but by no means universal, to give out results (whether good or bad) in a face to face consultation.

However, my own personal experience is that when I was given the result of my prostate cancer biopsy, which was positive for cancer, I was given the news by the hospital's top consultant.  But last year when I was given the all clear for throat cancer, the results were given by a young registrar. 

To me, it seems unlikely that they would ask you to see a nurse if the news was very bad; I would expect they would ask you to see your GP.  But I am just speculating.  Everyone here knows that the wait for results is simply agonising.
