Almost half of all cancer deaths are caused by preventable factors. This follows from a scientific study by an international research team, published by the medical journal The Lancet.
The researchers analyzed data from about 10 million people who died of 23 different types of cancer in 2019.
External risk factors were involved in 4.45 million deaths. The list of 34 risk factors for an unhealthy lifestyle is led by smoking, alcohol consumption and obesity, according to the findings Institute for Health Measurement and Evaluation (IHME) from the University of Washington in Seattle.
“This study illustrates that the burden of cancer remains an important public health challenge,” said Christopher Murray, director of the IHME and co-author of the study. “Smoking remains the leading risk factor for cancer worldwide,” he added.
The study also found that men had a higher risk of dying from cancer due to external risk factors (50.6 percent). For women, this risk is roughly a third (36.3 percent).
In addition to alcohol, smoking and obesity, risk factors for cancer include unprotected sex and exposure to carcinogenic substances in certain occupations.
