How long will my grandma live with emphysema?

My grandma is 65 or so, and she has been diagnosed with emphysema. She's never smoked, but her relatives did when she was a child. The doctor's have done lots of testing, and she's between stages 2 and 3. What can she do to make it a better, (we know it's a chronic illness) And how much would money would it... show more My grandma is 65 or so, and she has been diagnosed with emphysema.

What can she do to make it a better, (we know it's a chronic illness)
And how much would money would it take to get a lung transplant?
What is the life expectancy? The internet has been kind of useless so far...

Thanks!
