Fast acting Cancer

My Dad was diagnosed with lung cancer in Sep, 2000. Was treated with Chemo to try and stop the tumour growing in his lung and lymph nodes in his neck. Within two weeks of chemo treatment, they found 5 more tumours through out his upper body. So chemo didn't work that time. Again with chemo and now radiation. Tumours stopped growing for a few days but now has found two more tumours. He is going down hill fast. Has anybody had the fastest growing Cancer around? If so, how did you beat it? He is also on Morfin and I was wondering if taken long enough do you start to become distant or not know what's goin on around you? Thanks in advance, Lindy
