Science News reports that a well-established drug called DCA kills cancers by turning off their notorious immortality. Unlike developmental compounds, DCA has been used for many years to treat other illnesses and is therefore known to be safe.
Furthermore, it is off patent, so it can be purchased cheaply.
Scientists at the University of Alberta cultured human cancer cells outside the body and found that DCA killed lung, breast and brain cancer cells, but healthy cells were left alone. Likewise, rats that had been infected with human cancer showed drastic improvement over the course of several weeks.
An exciting development -- if it turns out to be true.
