Finally got through to the oncologist and he explained that he thinks the biopsy result was a false negative.
He thinks that the lesions look too damn much like real metastasized tumors to be anything else. And that if they were damage from backed up bile ducts, it would look different.
Further, he thinks that it may be worse to try to treat this than to let it 'run its course' with 'pain management' for 'quality of life'.
That's based on Penny being too weak to walk. Chemotherapy weakens you, and this would be worse.
Penny and I disagree, naturally enough. We believe that the weakness is from going almost two months without being able to eat much at all, and that her knees failing is part of their ongoing lack of cartilage. So, we're going to start enforcing her eating.
And, we'll see how things go. Once we get her in for the second biopsy, and they know what they're dealing with, we can go on.
I'm hoping it's the 5% of weird stuff, for a change. She still has a mass near her intestines, which is also probably cancer, and they'll deal with that too. Which is why the chemo might be so hard on her. We'll see. For now, though, it's gonna be 'what can we do to get her through this?' and 'How do we get rid of it?'.
We will not give up unless we are forced to do so.
