Treatable infections responsible for early 2M cases of cancer globally each year, study suggests

"Bacteria, viruses and parasites cause around two million cases of cancer in the world each year, experts believe," the Press Association/Guardian reports. According to the news service, "Scientists carried out a statistical analysis of cancer incidence to calculate that around 16 percent of all cancers diagnosed in 2008 were infection-related," and "[t]he proportion of cancers linked to infection was three times higher in developing countries than in developed ones."
