Sorry to hear about your Dad. I see that you are getting lots of good advice. Remember, that your Dad should be participating in the process by doing readings, etc., so that he bonds with the idea of natural healing. My Dad was always skeptical, and I have learned to just support my Mum rather than have her try things. They were always lead to believe that the docs know best. Even when my Dad finally realized what a big business cancer is, he did not 'get it' that he could take control of his own situation. Be calm and supportive; this is his trip.
