There
are no magic bullets in the fight against cancer: that's the first thing
every responsible scientist mentions when discussing a possible new
treatment, no matter how promising. If there were a magic bullet,
though, it might be something like dichloroacetate, or DCA, a drug that
kills cancer cells by exploiting a fundamental weakness found in a wide
range of solid tumors. So far, though, it kills them just in test tubes
and in rats infected with human cancer cells; it has never been tested
against cancer in living human beings. DCA ... is an existing drug whose
side effects are well-studied and relatively tolerable. Also, it's a
small molecule that might be able to cross the blood-brain barrier to
reach otherwise intractable brain tumors. Within days after a technical
paper on DCA appeared in the journal Cancer Cell last week, the lead
author, Dr. Evangelos Michelakis of the University of Alberta, was
deluged with calls and e-mails from prospective patients—to whom he can
say only, “Hang in there.” DCA is a remarkably simple molecule. It acts
in the body to promote the activity of the mitochondria. Researchers
have assumed that the mitochondria in cancer cells were irreparably
damaged. But Michelakis wondered if that was really true. With his
colleagues he used DCA to turn back on the mitochondria in cancer
cells—which promptly died. One of the great things about DCA is
that it's a simple compound, in the public domain, and could be produced
for pennies a dose. But that's also a problem, because big drug
companies are unlikely to spend a billion dollars or so on large-scale
clinical trials for a compound they can't patent.

Thank you Newsweek for this important article. Why haven't any other mass media reported this major story? Why aren't many millions of dollars being poured into research? Notice even Newsweek acknowledges the drug companies are not interested in finding a cure for cancer if they can't make a profit from it. Some suspect the drug companies have even suppressed cancer cures found in the past. For one amazing example of this, click here. More on DCA available here.
