Derek,
Hopefully, having posted, and as you receive replies, your mental state will ease, if only a little--just having someone to talk to about it helps!
I'm pretty sure I posted something with a similar title to yours, around May after having an 'unplanned' biopsy!
The worst thing for us Brits, I think, is the long waiting time to actually 'get into the system'--once 'in it', things move along and all our questions are answered, but it's that initial waiting and worrying.
Try and remember that it may well NOT be cancer, and even if it is, everyone's case is different and all have different responses to treatments.
This is the place to come and post to relieve some of that tension--everyone will comfort you and answer any questions which they can during this interminable waiting time.
Whereabouts in the UK are you by the way?
Brenda
