Thanks for your thoughts and advice!
Biopsy was done Friday. Core biopsy guided by ultrasound. They got 8 samples from one node. There are several apparently but that one in particular was of interest according to the doc doing the biopsy.
Now we wait. Ugh. I think that is one of the hardest parts ... waiting and not knowing. I feel like we can deal with whatever it is so long as we finally get an answer. He just wants to feel better. They said it can take up to two weeks... so we are going to keep ourselves busy with the kids, house etc.
Thanks again.
