Assessment of interventions to address the built environment

摘要

There were an estimated 12-7 million new cases of cancers which accounted for 7-6 million deaths globally in 2008, with about two-thirds of cancer deaths in less developed countries. Two previous comprehensive analyses of infections and cancers reported that in 1990 and 2002 about one in six cancer cases worldwide could be attributed to infectious agents. In The Lancet Oncology, de Mattel and colleagues provide an updated systematic analysis of the proportion of cancer cases attributable to infection globally and by region in 2008. Compared with the two previous analyses, the absolute number of cancer cases due to infection increased by about half a million since 1990, whereas the proportion of cancer cases attributable to infection remained stable at about 16-18%.
