A new analysis by the World Health Organization (WHO) indicates that more than a third of all new cancer cases worldwide could be prevented through lifestyle changes and other modifiable risk factors. In 2022, approximately 38% of nearly 19 million new cancer diagnoses were linked to preventable factors such as smoking, alcohol consumption, obesity, lack of physical activity, air pollution, UV radiation, infections, and occupational risks. Smoking was identified as the leading cause, accounting for around 15% of all new cancer cases globally and 23% among men. Alcohol consumption contributed to about 3.2% of cases, while air pollution had varying impacts depending on the region. Infections, particularly high-risk human papillomavirus (HPV) infections, were linked to roughly 10% of new cancer cases, especially cervical cancer in women. The study highlights the importance of vaccination against HPV and other preventive measures to reduce the global burden of cancer.
