Hi John.
I'm sorry that you've had to find us, but welcome to the forum.
It is normal to feel extremely anxious, especially during the initial diagnosis process. Waiting for results is one of the worst parts.
In the UK, it's usually 2 or 3 weeks for biopsy results, but that maybe different in America.
Time off work will be dictated by your treatment plan.
Please keep us updated. You'll get a lot of support here.
Best of luck pal.
