Some of you may have heard about a new drug called DCA that has flooded the Internet with buzz, conspiracy theories and frantic blog posts. For those who haven�??t heard about it, it�??s a drug that was recently discovered to shrink tumors in rats and kill cancerous human cells (in a petri dish). Long story short- it isn�??t getting the funding it needs for real human testing and FDA approval. Because it�??s so cheap to make and not patentable, pharmaceutical companies won�??t touch it.
