It's getting really tough I don't know how to help my father. We've been told he has a 8cm tumor on his liver in April. He was also recently diagnosed with Alzhemers. The treatment options are not suitable for him due to his age 84 yrs. Dr has prescribed morphine to help with the pain but he's recently started complaining of shortness of breath and feeling full and sick this is now daily thing. He keeps begging to be taken to the hospital. We've stopped telling him he has cancer because he forgets and we have to keep reminding him and the emotional toll it's taking is too much. What can I do to help him?
