I watched that move recently, hubby watched most of it. The best part IMO is the last section on immunotherapy. Other research I have done since hubby’s diagnosis has been on the immune system. Eliminating sugar, alcohol and tobacco are key - they all suppress the immune system. Also there have been good results in a Mayo clinic study on EGCG, the green tea extract. They had a 31% success rate on CLL getting the lymphocyte counts to decrease. Anything that can be done before the chemo process has to help.
Cantron (if taken exactly as directed) is the most powerful anti-oxidant on the planet as far as I know. Sugar feeds cancer is what I have been told.
