"Cheap safe drug kills most cancers"

I missed posting this when I first became aware of it. New Scientist wrote about a "cheap and simple drug that kialmost all cancers by switching off their 'immortality'."

All the drug does is change the metabolism of the cancer cell, which reactivates its normal self-destruct mechanism.

TheNew Scientist report from 2007 is here. I'll try to find follow information on how research is progressing.
