Study: One In Six Cancer Cases Worldwide Caused By Infections.

The CNN (5/9, Landau) "The Chart" blog reports, "One in six cancer cases worldwide are caused by infections, many of which are preventable or treatable, according to a study published Tuesday in the journal The Lancet Oncology."

        The ABC News (5/9, Moisse) "Medical Unit" blog reports that "French researchers pooled data on 27 cancers from 184 countries to calculate the fraction of cases attributable to viral, bacterial and parasitic infections." The researchers found that "human papillomavirus (HPV), hepatitis B and C, and the ulcer-inducing Helicobacter pylori caused 1.9 million cancers worldwide in 2008."

        The Minneapolis Star Tribune (5/9, Stoxen) "Health Check" blog reports that approximately "half of infection-linked cancers seen in women were blamed on cervix uteri cancers." Meanwhile, "among men in the study, more than 80% of cancers tied to infection were liver and gastric cancer."

        BBC News (5/9, Roberts) reports that "nearly a third of cases occur in people younger than 50 years." Also covering the story was Medscape (5/9, Mulcahy).

        HPV Linked To Increase In Oropharyngeal Cancers In Men. USA Today /WKYC-TV, Cleveland (5/9, Robins) reports, "In the past decade, oncologists have noted an increase in cancers at the back of the tongue, in the tonsils and into the throat, especially in healthy, nonsmoking men." Altogether, "more than 7,000 new cases of oropharyngeal cancers are diagnosed each year, according to the Centers for Disease Control and Prevention." The majority "are in men, and those who don't use tobacco often find another common cause: the human papillomavirus, better known as HPV."
