Hi, I have a dear friend that was told he had colon cancer about 3 years go. He was given radiation then one day while walking his leg fractured from the hip to the knee. Now he has been getting tumors in his lower limbs and is receiving chemotherapy every three weeks. Doctors have told me he is in stage four. Does the chemo work he is so frail thin and the chemo makes everything he eats taste awful. He lives alone and is fiercely independent, he never complains. He now has limited use of his lower limbs due to stiffness. I need to know how long is his life expectancy and what can I do to make him as comfortable as possible, he has no family. I am much younger than him and i cant understand why I cant get a straight answer from the doctors.
