I read your question and wasn't sure about replying, as I have had Chemotherapy (CHOP). While I admire your courage in going for a natural solution, I think I should tell you that the chemotherapy
seems to have worked well for me (I had it 2 years ago). The tumors started to shrink straight away, even the odd wart that I had quickly disappeared. Maybe its worth reconsidering?
Anyway, whatever you do I hope all goes well and wish you luck - that is often the most useful thing to have!
