Scientists Find Way to Prevent Lung Cancer 


Scientists have discovered that a "chemoprevention" regimen was effective on male mice in preventing tobacco-smoke-related lung tumors, according to an April 26 press release from the National Institutes of Health (NIH).  Researchers Hanspeter Witschi, Dale Uyeminami, Dexter Moran and Imelda Espiritu from the University of California at Davis found that a diet regimen containing myoinositol and dexamethasone proved successful in protecting mice exposed to cigarette smoke.

Myoinositol is derived from cereal brans, while dexamethasone is a corticosteroid drug. According to Dr. Witschi, the regimen worked in mice when given during the five months of exposure to tobacco smoke or in the weeks afterwards.

The scientists hope the research would lead to measures that prevent lung cancers in humans. The study is reported in the journal Carcinogenesis.
