Health Canada warns Canadians of cardiac risks associated with cesium chloride

"Health Canada is warning Canadians that the use of stable cesium compounds (non-radioactive form of cesium salts, primarily cesium chloride) may pose the risk of life-threatening heart problems. Cesium, primarily in the form of cesium chloride, is promoted on the Internet to prevent various forms of cancer and as a self-administered cancer treatment. While use of radioactive cesium in radiation treatment for cancer is authorized in Canada, Health Canada has not authorized any health products containing stable cesium compounds for oral or intravenous use, including cesium chloride. However, numerous Internet sites promote the oral use of cesium chloride as an alternative to chemotherapy. In addition to the risk of life-threatening heart problems, there is inadequate evidence to support claims of benefits with this type of treatment. The decision to self-administer cesium chloride as a treatment for cancer may also delay the start of authorized therapies that have been proven effective."
