My best friend is dying from prostate cancer, it's only a matter of a few months, if that long. My wife and I went to the doctor with him and his wife today, in order to help out, as he is too weak to hardly stand. It's very hard watching him slowly waste away, but he is ready to go. and knows where he's going when he leaves this world. About all you can do in cases like this is to just be there and let the person know that you'll do whatever you can to help out.
