Kevin,
I believe you are at the best place you can be. The curezone has been invaluable to me as a resource in fighting my metastatic melanoma. I would recommend that you review the "150 things you can do" section of this website and print out what might be acceptable to your friend and grandmother. For example, there are dietary changes that she should make and if someone is willing to help her juice, that would be a great start. Time is of the essence and multiple therapies are their best hope.
If you want specifics, respond to this msg. and I will tell you what I've done.
