When my doc found the cancer with a biopsy, I had the choice of waiting two weeks for surgery (until he came back from Japan and I came back from The Cape (previously planned) or finding another doc to take the mass out possibly sooner. I chose to wait because of my confidence in the doc. Two weeks was hard enough to wait with my uncle saying in my ear "when exactly does cancer metastacize?????"
I couldn't imagine waiting six. I agree with MK, a biopsy can be done there (this is assuming that histology is a biopsy, that's probably what it is, though). Sounds like a to-be-sure biopsy is a good idea. Keep us posted. and I'll be praying for you.
