Yeast fights cancer?

I don't know what to make of this..... (UPDATE - I pointed this out to Seth Roberts and he blogged about it)

A researcher at Charles Drew University of Medicine and Science is investigating the potential use of non-pathogenic baker's yeast as a promising, natural therapy for cancer.

For more than two decades, Dr. Ghoneum has pursued a theory that cancer cells self destruct when exposed to small quantities of yeast.

In laboratory tests, Dr. Ghoneum exposed cancer cells to yeast and observed as they ingested the yeast -- through a process known as phagocytosis -- and then the cancer cells died. First, he investigated this phenomenon in test tubes (in vitro), introducing yeast to breast, tongue, colon, and skin cancers.

"I have no doubt that I am close to unlocking the mystery as to why cancer cells weaken to the point of destruction after eating common baker's yeast," Dr. Ghoneum said. "The cells just gravitate to the yeast. I call it fatal attraction."
