My colon cancer is in stage four with metastases in my liver, lungs, prostate, bladder, and pelvic bones. The surgeon removed it four years ago, but it came back with a vengeance. The chemo and radiation were not my choice, and I would have used chlorine dioxide water treatment drops instead of the original surgery if I had made the studies I have since then. Although I have tried a lot of things on my journey, chlorine dioxide has been the only thing that has worked for me.
