Hello, I'm posting this on behalf of my dad who has Stage IV lung cancer which has spread to the bones. He started a cesium chloride treatment about 1 month ago. He is still in tremendous pain and very weak. Apparently the fact that he is in pain means that the cesium chloride is working and that the cancer cells are being destroyed. Did anyone use this drug? How successful was it? How did you feel while taking it? Any input/thoughts would be greatly appreciated.
