Scientists discover how cigarette smoke causes cancer "Everyone has known for decades that that smoking can kill, but until now no one really understood how cigarette smoke causes healthy lung cells to become cancerous. In a new research report published in the March 2008 print issue of The FASEB Journal, researchers from the University of California, Davis, show that hydrogen peroxide (or similar oxidants) in cigarette smoke is the culprit. This finding may help the tobacco industry develop ‘safer’ cigarettes by eliminating such substances in the smoke, while giving medical researchers a new avenue to developing lung cancer treatments."
