Cancer card

What the hell do you write in a card to someone who’s just been diagnosed with terminal cancer?

“Get well soon” is traditional, but hardly seems appropriate in the situation. Anything involving the word “sympathy” sounds like I’ve got the headstone and lilies ready. “Hope your death is speedy and painless” is the best the doctors say it’s reasonable to hope for, but isn’t exactly appropriate for a card. I can’t write “You are in my prayers” for obvious reasons. The best I can come up with is “Hope you’re feeling better”.

I’ve never been good at this kind of stuff.
