One of my relatives cured himself of prostrate cancer with cesium drops under the tongue.
Another relative of mine just died of stage 4 liver cancer. I was trying to get them to use the DMSO/ Cesium Chloride protocol but they just didn't follow through. Sadly this is what happens most of the time. Sometimes you have to do it all for them. They just don't have the will to act.
