What is Cesium?

Cesium is an element. In its natural state, cesium is not radioactive. However, it can be made radioactive in the laboratory. People use both forms of cesium for medicine.

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. But these claims are not supported by science. There is no scientific research that indicates tumor cells differ in pH from normal cells or that cesium affects the pH of tumor or normal cells.

Non-radioactive cesium is also used to treat depression.

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.

Insufficient Evidence to Rate Effectiveness for...

More evidence is needed to rate the effectiveness of cesium for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
