Three years ago, a team of scientists from Harvard University raised concerns about a possible 'global epidemic' of early-onset cancers. They detected an increase in 13 types of tumors in people aged 20 to 49 years from 2002 to 2012, suggesting causes such as sedentary lifestyle, obesity, and the consumption of unhealthy foods and beverages. However, a recent study led by Spanish epidemiologist Montserrat García Closas offers a more nuanced perspective. Although cancer cases are increasing among young people, this phenomenon is not limited to a 'global epidemic' specifically for them. Obesity-related tumors, such as colorectal, thyroid, kidney, and breast cancers, are also increasing among people over 50.
García Closas's study, which reviewed data from 42 countries between 2003 and 2017, notes that although there is an increase in some types of cancer among young adults, four types (stomach, esophagus, mouth, and liver) show an annual decrease, possibly related to a reduction in alcohol consumption. The epidemiologist highlights the importance of not focusing exclusively on young people, as cancer remains predominantly a disease in older adults. The panorama requires an integrated action of prevention and detection across all age groups. As the debate about a 'global epidemic' continues, the call is to intensify research and promotion of healthy lifestyle habits.
