DCA Siebenhüner The substance DCA (dichloroacetate, dichloroacetic acid) is an agent that has been used in the treatment of metabolic acidosis disease for many years, but has not been approved as a drug. Research at the University of Alberta in Edmonton, Canada, showed cell cultures kill cancer cells but not normal cells. The experiments also showed that mitochondria (cell structures for energy production in the cell), which was thought to be irreparably damaged by DCA were functional again. Since mitochondria are also responsible for triggering the so-called apoptosis, the natural cell death in addition to the energy production in the cells, this apparently led to the death of tumor cells. In the following animal experiments it led to the shrinking of malignant tumors. Since DCA engages in the tumor-specific metabolic fermentation and induces apoptosis in the cancer cell, it is now being used for some time in cancer therapy. There are thus far, unfortunately no official studies to DCA. Whether a fermentative metabolism is present in our patients, we see by special individual blood tests before treatment. In the positive case DCA therapy is necessary in order to block this fermentation metabolism of the cancer cells and thus to block the growth of the cancer cell. The side effects such as occasional disorders at the nerve endings form slowly after discontinuation of the agent. Our center of advanced medicine in Frankfurt am Main/Germany is specialized to recognize this side effect and to avoid them.
