Goes to show that sometimes we only get a part of the story.. the aunt who was 104!
I also had someone tell when the day after I was diagnosed that an in-law of hers who had cancer and the doctors couldn't go any more for him! so he went all vegan etc.. watched everything he ate, and he is still alive! A couple of years later I revisited that story with her and asked her more specifically, about him and turned out he had all his chemo and everything, did everything the doctors told him. However the initial conversation she made out it was the healthy diet that "saved" him. She herself is a naturopath. Partial stories are never helpful, but thankfully I didn't listen to the quacks, but I listened to my medical team.
