Seven million people's cancer could be prevented each year, according to the first global analysis. A report by World Health Organization (WHO) scientists estimates that 37% of cancers are caused by infections, lifestyle choices, and environmental pollutants that could be avoided. This includes cervical cancers caused by human papilloma virus (HPV) infections, which vaccination can help prevent, as well as several tumors caused by tobacco smoke. The researchers emphasized that there is a powerful opportunity to transform the lives of millions of people through effective cancer prevention strategies.
While some cancers are inevitable due to genetic factors or aging, Dr. Isabelle Soerjomataram pointed out that many people are surprised to learn that nearly four in ten cancers can be prevented. The International Agency for Research on Cancer analyzed 30 identifiable risk factors known to increase the likelihood of cancer, including smoking, obesity, lack of physical activity, and air pollution. The report identified tobacco smoking, infections, and alcohol use as the top three preventable causes of cancer globally.
Moreover, the study highlighted significant regional disparities. For instance, 45% of men's cancers are deemed preventable compared to 30% of women's cancers, attributed mainly to higher smoking rates among men. In sub-Saharan Africa, infections account for nearly 80% of preventable cancers in women, further stressing the importance of targeted prevention efforts. This landmark study incorporates infectious causes of cancer along with behavioral and environmental risks, showcasing that resolving these preventable causes offers a vital opportunity to mitigate the global cancer burden.
