I assume you have exhausted your standard medical options at this point.
I have no experience with Anvirzel, but I have several patients who treated themselves into remission with dramatic diet change alone. Additionally, there are literally dozens of natural products with research supporting their use in cancer treatment (Reishi extracts, Omega-3 oils, glutamine, vitamin D, vitamin C, ginseng, etc.) I did not find extensive research on Anvirzel. Please realize that it is only one alternative among many.
I hope this helps. Chris Maloney, Naturopathic Doctor www.maloneymedical.com Private research available for a fee.
