Hi Simon,
You seem to be reacting in a very calm and measured way.
I know how hard it is to stay level when you start hearing and seeing the word cancer in your medical discussions.
I tried to be as rational as possible but I'd be lying if I said worry didn't creep in.
All I can say is take things one test at a time, wait for the results and move on.
This is the hardest part of the journey as, like me, you have to learn a whole new language to pick your way through the tests and it's a long waiting game as results lead on to other tests or not as the case may be.
This place is a real help and there are guys on here, like Adrian, who have been there and got the tee shirt, fridge magnet and straw donkey. They won't lead you wrongly.
Take care and keep chatting
Mick.
