Thank you all for your feedback. The hospital called today to say I need to do bloods and have a CT scan of chest. Once done, they will discuss results and call me sometime next week. Long wait!
I think it was the way the Endoscopist and senior nurse spoke to me on Saturday, using words like "highly suspicious", "it looks nasty", "don't give up hope", "I feel for you, my mother in law just died"!
The person I spoke to today was less dramatic albeit cautious which I understand. Anyway, your thread OP is beginning to feel like a support group x
