Nearly half of all cancer deaths are preventable

Up to 44 percent of all cancer cases in the world are due to avoidable factors, such as smoking, pollution and alcohol consumption.

one appears Great new studywhere American researchers, among other things, examined numbers of cancers and deaths in 204 different regions of the world.

The review reveals that 4.5 million cancer deaths in 2019 were due to factors that could have been prevented.

According to the researchers, smoking, alcohol consumption, and high body mass index (BMI) still bear the bulk of the responsibility for deaths globally, confirming the results of several smaller studies.

Here are the top ten risk factors

In the new study, one of the largest of its kind, researchers carefully examined the relationship between 23 different types of cancer and 34 preventable risk factors, such as secondhand smoke, physical inactivity and a diet low in whole grains.

Among other things, this made it possible to identify and categorize the 10 risk factors that led to most people losing their lives in 2019 and compare them with the figures for 2010.

Smoking, alcohol and a high BMI occupy a sad place in both years. At the same time, the number of deaths from obesity accounts for the largest increase during the period – Especially in low-income countries.

Men are the most dangerous

Cancers of the trachea, trachea, and lungs are at the top of the preventable cancers that kill most people. Rectal cancer and esophageal cancer end in the places immediately following.

The researchers also discovered a significant difference between the sexes. While 50.6 percent of all cancer deaths among men could have been prevented in 2019, the corresponding figure for women was 36.3 percent. The researchers behind the study do not provide an explanation for what caused the difference.

else Experts speculate However, men and women may react differently to risk factors for biological reasons, and some researchers also suggest that cultural differences in behavior may play a role.
