My father lived almost 6 years after diagnosis. He saw his younger daughter and first grandchild get married and he got to London, Paris and Rome. He also was able to live independently and take complete care of himself right up to the last two months -- cooked, shopped, enjoyed Starbucks visits, his Netflix... In the end, he really fought dying. He did not want to "go". Was it worth the treatments to my Dad? Yes, without a doubt.
