Cesium is chemical element used in the form of cesium chloride as a purported alternative therapy treatment for different cancer types. There is no clinical or scientific evidence that cesium chloride can be useful for cancer, states Memorial Sloan Kettering Cancer Center. This purported cancer treatment is promoted as a high pH therapy, which is said to lower the acidity level of cancerous tumor cells, states WebMD.
However, there is no scientific prove that this claim is true about cesium being able to affect the pH level of tumor cells. The pH therapy involves patients taking oral supplements of cesium chloride.
In some people, cesium chloride may have negative side effects when taken in high doses, such as diarrhea, nausea, no appetite, tachycardia, tingling of the extremities and hypokalemia, states WebMD. Additionally, pregnant or lactating women should not use this supplement.
Patients with an irregular heartbeat should not use this supplement because doing so may exacerbate the condition further. Similarly, patients, who take either corticosteroid or diuretics, should avoid using cesium chloride due to a possible drug interaction. Combining these medications with cesium chloride may result in a decrease in the body's potassium levels, which can lead to hypokalemia.
Cesium does have some uses in the medical field. For example, a radioactive form of cesium, which is an alkali metal, is used for radiation therapy. Cesium chloride is a salt compound that is stable and not radioactive, notes Memorial Sloan Kettering Cancer Center.
