![]() A 2009 study published in the Journal of Medical Physics, discusses using cesium-131 seeds for treatment in prostate cancer with positive results.Īnd while more research is still needed to understand more about the treatment, all of the studies have shown that using cesium-131 brachytherapy seeds for cancer therapy is encouraging. According to Isoray Medical, cesium-131 was FDA-approved in 2003 with the first trials in 2004. The idea for using cesium-131 brachytherapy seeds as a treatment for cancer dates back to the 1960s and was described in a study published in the journal Radiology. There were minimal side effects, and it was overall a well-tolerated form of treatment. In the earlier study, a group of 24 patients with brain tumors had cesium-131 brachytherapy seeds implanted within the tumors. The above study refers to a previous study published in 2014 in the Journal of Neurosurgery. Brachytherapy seeds have been shown to be effective in several forms of cancer including prostrate, cervical, and endometrial cancers. According to the American Brachytherapy Society, a brachytherapy seed is a radioactive pod that is placed directly within the cancerous tissue. Cesium-131, a radioactive isotope of cesium, is used with iodine-125, another radioactive isotope, in a brachytherapy seed. While it is unlikely that people will experience adverse health effects just due to the cesium, exposure to radioactive cesium or certain cesium compounds can lead to adverse health effects including nausea, vomiting, bleeding and cell damage.Ĭesium is currently being researched in treatment of several forms of cancer, including brain tumors, according to a study published in 2016 in the journal Frontiers in Surgery.
