I can understand her need to want her grandmother to be well but face reality. This is cancer. The treatment itself is horrible and devastating. Grandma is old. Can she even survive the treatment? Do you want her to live the rest of her life in pain of treatment on the off-chance she may live another few more years? If it was guaranteed it will wrok and/or they are filthy rich, not an issue. In caes like this, you also need to ask the patient. What is her desire?
