I think Rush mentioned that his lung cancer had metastasized to his kidneys or liver.
When that happens, it’s only a matter of time; and unfortunately, his time is running out. If he makes it another six months, I’d be surprised.
My petite wife, literally “the girl next door”, had breast cancer at 28 and when it metastasized to her liver, her stomach swelled as if she was 9 months pregnant.
It was over after 7 months - from diagnosis to the end. The silver lining was only the last 2 months were painful.
Yep, once it hits the liver, remaining time is very short.
