With these three, the death of nearly half of the cancer can be guarded!

A maximum study of the relationship between cancer burden and risk factors shows that nearly 50%of the world's cancer deaths are caused by preventive risk factors, such as smoking and drinking.

Through the estimation of cancer cases and cancer death cases in more than 200 countries, researchers have found that the avoided risk factors have led to nearly 4.5 million cancer death cases in 2019, accounting for more than 44%of the global cancer deaths.

Rudolf Kaaks, a cancer epidemiologist at the German Cancer Research Center, said the research results published on August 20 in "Liu Ye Dao" have confirmed the results of some small -scale research to a large extent and emphasized the reduction of exposure to exposure to exposure to exposure to Under risk factors, it helps prevent a variety of cancers.

In short, "Don't smoke, don't overweight, don't drink too much wine."

The above -mentioned author, Justin Lang, an epidemiologist at the Canadian Public Health Agency, pointed out that it is difficult to determine the world's cancer cases and the real figures of death, because some countries have not recorded these data.

To overcome this issue, Lang and colleagues used a research data for more than 350 diseases and related deaths and disability in 204 countries.

Based on these data, they estimate the impact of 34 risk factors on health issues and 23 cancer deaths.

Studies have found that in 2019, half of male cancer cases and more than 1/3 of female cancer cases are due to preventive risk factors, such as smoking and drinking, unhealthy diet, unsafe behavior, and contact with harmful substances in the workplace. dead.

From 2010 to 2019, global cancer death cases caused by the above risk factors increased by about 20%, of which the proportion of overweighting deaths has increased the largest, especially in low -income countries.

"Combining the results of the above research with the local situation may help decision makers determine the cancer risk factors that should be targeted in the cancer control planning work." Research on Kelly Compton said.

Senior author and IHME researcher Lisa Force said that it has proved that it is effective in reducing smoking policy, increasing tobacco taxes and smoking -proof advertisements. At present, similar measures are also recommended to help reduce excessive drinking.

The study does not include other known cancer risk factors, such as ultraviolet radiation exposure and certain infections.

However, researchers said that once related data, they will incorporate the above factors into analysis.
