"The study leads with a statistic as striking as Soerjomataram's opening claim: 7.1 million new cases of cancer were linked to what's known as modifiable risk factors (MRFs) such as consuming tobacco or alcohol, as well as various infections. That's 37.8% of a total of 18.7 million new cancer cases in 2022. Research into MRFs is not strictly new. We have long known that MRFs, which also include overweight and obesity, air pollution, and other environmental toxins, can be carcinogenic."
"The authors considered 30 MRFs, including tobacco, alcohol, air pollution, and occupational exposure to toxins such as asbestos, as well as: A high body mass index (BMI) Insufficient physical activity Smokeless tobacco and areca nut Certain breastfeeding practices Ultraviolet radiation (UVR) And, for the first time in a study involving MRFs, the researchers also included infectious agents, such as hepatitis B and human papillomavirus (HPV)."
Research involving 36 cancer types across 185 countries found that 7.1 million new cancer cases in 2022—37.8% of 18.7 million total—were linked to modifiable risk factors. Thirty modifiable risk factors were evaluated, including tobacco, alcohol, air pollution, occupational toxins, high body mass index, insufficient physical activity, smokeless tobacco, areca nut, certain breastfeeding practices, and ultraviolet radiation. For the first time in this context, infectious agents such as hepatitis B and human papillomavirus (HPV) were included among modifiable risks. HPV-related preventable cancers remain high in some regions and represent the largest share of preventable cancers in women despite effective vaccines.
