The newly-released Lancet study says lifestyle risk factors such as smoking, drinking and obesity caused nearly half of cancer deaths in 2019. Risk factors differ globally based on environmental and economic conditions.
According to a recently published Lancet study, lifestyle risk factors like smoking, drinking, and obesity were responsible for over half of all cancer deaths in 2019. Based on prevailing economic and environmental conditions, risk variables vary widely. Controlling risk factors including smoking, drinking, and having a high body mass index could save cancer deaths, according to a recent study published in the British journal Lancet.
The study identified a collection of risk variables, which included behavioural choices, that together accounted for 44.4% of all cancer-related deaths globally in 2019.
Researchers discovered 34 risk variables, with obesity, drinking, and smoking being the most prevalent. About 33.9% of cancer cases were caused solely by smoking.
The analysis of 10 million cases of cancer deaths from 23 distinct categories in 2019 led to these conclusions.
Christopher Murray, a co-senior author of the report, noted that the burden of cancer “remains a significant public health concern that is expanding in magnitude around the world.”
Different Results in Low-income Countries
The study also concluded that causes of cancer deaths varied based on the location and Socio-Demographic Index of the countries where patients reside.
The life expectancy of cancer patients was significantly impacted by characteristics including smoking, risky sex, and alcohol consumption in lower income countries.
Metabolic hazards had a significant impact in South Asia, the Middle East, North Africa, and Sub-Saharan Africa as well. On the Social Demographic Index, the regions all have poor rankings.
While the study’s findings suggest that regulating behavioural factors may be able to prevent a sizable portion of cancer deaths, other factors were not as easily managed, according to the study’s findings.
It advised taking action to facilitate early diagnosis and efficient treatment.
