In July 2011 I was diagnosed with Stage IV colon cancer which had metastasized to the liver. On the advice of my naturopathic oncologist, I started taking Anvirzel® immediately after surgery to remove part of the colon. I believe Anvirzel® allowed me to get through 6 months of chemotherapy with no problems. I was not nauseous, had energy & did not lose my hair. The blood marker (CEA) used in colon cancer dropped dramatically every month. A recent MRI has shown all spots in the liver are gone. I believe Anvirzel® played a very important part in my recovery.
