I have been taking modified citrus pectin in tablet form. I take 4 tablets a day. These are supposed to attack cancer cells and kill them. I don’t know if they are doing me any good but I’m still around and my cancer is in remission and this has been from not taking any chemo for the past year. MCP can be bought at your health food store. The cost to me is $120/month Canadian. I also do not smoke, drink, and try to eat mostly vegetarian.
