Thanks to everyone for your support and advice.
We got the biopsy results today. The liver growths were, in fact, malignant. There's also a growth on his colon. Next Tuesday, they're gonna remove that, too. That same doctor told me that it WILL be malignant.
They'll treat him agressively with chemo and we're determined to keep a positive attitude.
God will watch over him. I just know it. I cannot lose him.
