Depends upon the intent. Most people only say or do things to make themselves feel better in situations like that.

I'd guess the person knowing how important, loved or whatever they were has some benefit but it's hard to say for sure if anything other than "Turns out the doctor was wrong" will make them feel any better.

tell them to make the best of the time they have and do everything they wanted to do but were to afraid to.  There is not much you can say to make the pain nd shock go away.  Just be there and be supportive.

I'd tell them to live each day to the fullest. To go on that vacation. To buy that item that you always wanted. Life is too short.

I never know what to say in these situations.
