Is cesium chloride safe for cancer treatment?
Despite serious safety concerns, non-radioactive cesium is taken by mouth for treating cancer. This is sometimes called “high pH therapy.” According to people who promote high pH therapy, taking cesium chloride by mouth reduces the acidity of tumor cells (raises their pH), which are described as very acidic.
Does cesium chloride raise pH?
This is sometimes called “high pH therapy.” According to people who promote high pH therapy, taking cesium chloride by mouth reduces the acidity of tumor cells (raises their pH), which are described as very acidic. But these claims are not supported by science.
What is radioactive cesium (cesium-137)?
Healthcare providers sometimes treat cancer patients with radioactive cesium (cesium-137). In industry, radioactive cesium is also used in instruments that measure thickness, moisture, and liquid flow. How does it work?
