Chelation

In my opinion available scientific evidence does not suggest a benefit to chelation treatment for patients with cancer and safety is an important factor to consider. Some laboratory studies have suggested that agents that chelate copper or iron may affect cancer cells or the formation of tumor blood vessels but there is no robust evidence for clinical benefit with chelation. Chelation therapy also may have safety concerns. Chelation therapy may produce toxic effects, including kidney damage, irregular heart beat, nausea, vomiting, diarrhea, and temporary lowering of blood pressure. Since the therapy removes minerals from the body, there is a risk of developing low calcium levels (hypocalcemia). The possible interactions between chelation therapy and chemotherapy and other prescription or over-the counter medications are not well known.
