my grandpa is 73 and had not eaten in over a month and then was sent to hospital. They ended up cutting him open and has to attach small intestine to large and removed large tumors.. he didn t recover well so they did surgery again found more tumors and gave him a collostomy bag because tumors were blocking it up. He is now home and real weak. He just saw onocologist who says his kidneys are weak and he still too weak for chemo and that his cancer is stage 4... what can we do to improve his chances?? And what are his chances of recovery??
