My Close Friends Husband Has Liver Cancer

My close friend's husband has liver cancer, colon cancer,kidney stones now his spleen is very enlarged and the doctors have sent him home to die and my friend hasn't been told as what to expect,time wise etc. and has asked me to see what I can find out for her. She just wants to be on top of things and can't quite get the answers from their doctor. Can you tell me anything that will help her she has taken care of him for so long and is trying to keep on top of things but is getting very worried as he's in a lot of pain and his stomach is very swollen and can't eat very much. He's on very strong pain meds.
