Hi Nikki,
So sorry to hear about your dad's dx. I'm a lung cancer survivor, but my dad was dx'd with bladder cancer when he was 82. He also refused chemo, and lived three more years rather well. After going through chemo myself at 45, I can say that I don't think my dad would have survived it. Continue being a supportive daughter to both your parents, and I'll keep you all in my prayers.
Betty
