Sorry to hear your news mate, I lost my Grandad, my Uncle to cancer and almost my aunt to cancer, horrible thing to see perfectly healthy people (Grandad was a strong farmer type and uncle was a game keeper, keen fisherman etc) reduced to bags of bones like you say. Still brings a tear to my eye when I think of my Grandad that way, like to remember him as the big strong bloke always happy to help everyone, taught me a lot in life he did. Hopefully some day soon they will find a cure for this horrible disease. I really do feel for you mate because I've been there a few times.
