@dlowan,
Back from Bellevue.
They couldn't do the biopsy. Why? Because the little mass turned into an air bubble, and as the doctor so wisely stated, "You can't get a biopsy of air."
What does this mean. Dunno. It could mean that the mass is evolving. It could mean that it's not cancer but an infection. It could mean any number of things.
The biopsy doc called my cancer doc. She's away on vacation.
So right now I don't know nuttin'. But I have a feeling that this is going to be a let's check it again in a month kinda thing.
