All good questions, some of which can never be answered. As for the others, I am no longer in contact with this patient. This was part of an informal study which I used to satisfy myself that Cantron was a valid cancer treatment. I learned that performing such a study is extremely time consuming even though I limited the questions asked of the patients to ten. I can say that such a study is much more useful than testimonials where the failures seem to be completely missing.
