According to a large study published this Friday in “The Lancet”, tobacco is by far the main element that has favored cancer (33.9%), followed by alcohol (7.4%).
Nearly half of cancers worldwide are attributable to a given risk factor, primarily tobacco and alcohol, concludes a gigantic study published Friday, emphasizing the importance of preventive measures without making it a panacea.
“According to our analysis, 44.4% of cancer deaths worldwide (…) are attributable to a risk factor that has been measured”, advances this study, published in the Lancet and carried out within the framework of the Global Burden of Disease.
This vast research program, funded by the Bill Gates Foundation, is of an unparalleled scale, involving several thousand researchers in most countries of the world. This work therefore makes it possible to know more in detail the risk factors according to the regions of the world even if, on the whole, its conclusions confirm what was already known: tobacco is by far the main element having favored cancer (33, 9%), followed by alcohol (7.4%).
Prevention is not enough
Above all, these conclusions argue for giving a great deal of importance to prevention in public health, since many of these risk factors relate to behaviors that can be changed or avoided.
However, a good half of cancers are not attributable to a given risk factor, which shows that prevention is not enough. This, according to the authors, must therefore be accompanied by two other pillars: a sufficiently early diagnosis and effective treatments.
In an independent commentary, published in the same edition of Lancettwo epidemiologists supported these conclusions, also believing that the study underlines the importance of prevention.
