Got her results back earlier today:
She has stage 4 small cell cancer (can't remember the actual name for it) that appears to not only be in her brain, but in her left lung and abdomen as well. They're not recommending surgery. She'll do radiation for 2 weeks then 3 weeks of chemo to do what it can. The steroids she's on has shrunk the one in her brain to a much smaller size, so that's good, but...dammit.
They sent her home with me earlier today instead of making her wait the whole time in the hospital, so I'm going to be busy with her for a bit.
I'd still sorta numb over this, but I'm angry as well. She had a full PET scan in February, but never called back to get the results or even followed up with her doc.
But, we're going to do all we can and hope it goes well.
I do want to give another huge and heartfelt thank you to everyone here, and to those who I've talked to since we found this out. I honestly do appreciate it.
