I dont think it does to be honest! I would suggest your mother eating a pineapple everyday for the Bromelain enyzme to help strip stealthy coated cancer cells of this sheath and then other treatments can get to work on the cancer. Your mothers immune system should be boosted with 30mg of Zinc and if possible Anti-Oxidants. The problem is once you get on the establishment toxic drugs the helpful healing of Nutrition takes longer because of the initial poisoning. I would suggest you look in Ozonation of Water especially if its in the stomach.
