Cesium Chloride is one of the best minerals I know of to boost your PH up to alkaline. Being cancer thrives in an acid environment, turning you body to alkaline is the very first thing you should do to stop the spreading of the cancer. I think that Cesium Chloride is great. It is one of the tools that Dr Kelley used in his metabolic program that had a high success rate..... over 80 percent.
