Firstly, I very, very much hope that your docs are mistaken and that this is nothing to worry about.
Whatever the result I severely doubt that you'd be allowed the answers in any way but face to face I'm afraid.
IME the result appointment gives you the chance to ask questions, discuss options and so on. For example, I was told that I'd have radiotherapy and not chemo and was offered the choice of having all the lymph nodes remove from under my arm or just the first couple.
It's also a chance to discuss the matter with family - if you have a DH/DP or friend with you for that matter they may have concerns they wish to have answered - an if you take a friend they will probably be more able at that stage to ask questions, argue a point for you (when my doc suggested the removal of only 1 or 2 lymph glands to examine, with the idea that they'd have me back in for the removal of the rest if they were found to be diseased, my lovely friend spoke out, "She's needle phobic, has 2 little children and is bloody petrified for gods sake, don't potentially make her go through it twice!"
If I loved my dear pal before, I loved her even more at that moment.
There is much to go over and the nurses are incredibly supportive and specialists in their field, you'll value them I'm sure. Besides, this isn't something to be borne alone lovey, if the result is bad news.
I pray to whatever gods up there that this is a false alarm but, if you ever want to talk/vent/scream, don't hesitate to pm me.
