Cancer deaths could be prevented by controlling risk factors such as tobacco consumption, alcohol consumption, and high BMI, a new study by the British journal Lancet has concluded.

The study attributed 44.4% of global cancer deaths in the year 2019 to a group of risk factors which included behavioral choices.
Researchers found 34 risk factors, with smoking, drinking, and obesity taking the lead. Smoking alone was responsible for some 33.9% of cancer cases.
Findings were based on studying the cases of 10 million people who died in 2019 from 23 different types of cancer.
“The burden of cancer remains an important public health challenge that is growing in magnitude around the world,” said Christopher Murray, a co-senior author of the study.
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.
In lower income countries, factors such as smoking, unsafe sex and alcohol use highly impacted cancer patients’ life expectancy.
In South Asia, the Middle East and North Africa and Sub-Saharan Africa, metabolic risks were also quite influential. The regions all rank low on the Social Demographic Index.
The study said in its findings that while its results point at the possibility of preventing a significant number of cancer deaths through controlling behavioral factors, other factors could not be as easily handled.
It recommended efforts towards supporting early diagnosis and effective treatment.
