City,
Yours is a rather common situation.
When the doc takes that first biopsy sample s/he is basically blind as to the depth of the tumor. There is a balance between digging too deep and not enough.
Now, the doc knows where to take the next biopsy - after you heal a bit - and that the sample needs to include deeper tissue. The pathologist needs "clean margins" - non-tumor material surrounding the tumor - to make the true diagnosis. It is good that that is already planned.
Waiting is perhaps the most nerve-wracking part of BC. We can't see it, can't feel it, but we know it is there, and instead of actively fighting it we are told to wait. Frustrating. But the doc needs full info to properly treat it.
Try to relax, try to ignore the worrisome thoughts. Continue as normal, while planning ahead for the repeat TURBT. You are on track with many of us who have been there, this is a common (frustrating) occurrence.
Best,
Jack
