Chelation therapy involves injecting or consuming chelating agents for the purpose of removing undesirable substances, such as fatty plaques, mineral deposits, chemical toxins, and heavy metals, from the body.
One article (1) discussed chelation therapy and the treatment of cancer. Chelating agents involve anything that can bond chemically with chemical toxins, minerals, or metals, inside the body. When toxins build up, they can overwhelm the liver and may cause a buildup of toxins that go on to cause cancer.
The article cited a research study out of Switzerland, in which chelating agents were given to patients suffering from cardiovascular disease or cancer. They found that there were 90 percent fewer deaths from cancer and 86 percent fewer cases of myocardial infarction in those patients that took a series of twenty chelation treatments.
