Colorectal cancer, traditionally considered a disease of the older population, is escalating among younger people globally. A recent study reveals a worrying uptick in cases, particularly among those aged 25 to 49. What was once a pattern noticed primarily in the United States and other wealthy nations is now a global concern, with nations like New Zealand, Chile, and Puerto Rico experiencing significant surges. What’s fueling this alarming trend?
According to the study published on December 11 in Lancet Oncology, American Cancer Society researchers analyzed data from 50 countries. They found a rise in colorectal cancer rates in 27 of these nations over the past decade. Notably, the U.S. reports an annual increase of 2.13% in early-onset cases, with New Zealand leading with a staggering 3.97% per year rise. This increase in younger populations coincides with declining rates in those aged 50-74, suggesting age-specific factors at play.
The spread of colorectal cancer among the young appears to parallel the adoption of ‘Western lifestyles.’ Experts suggest that the rise in wealth and rapid economic growth in countries, coupled with a shift towards diets high in fast and ultra-processed foods, may be contributing to this health crisis. Dr. Marios Giannakis, an oncologist at the Dana-Farber Gastrointestinal Cancer Center, points to ‘inflammatory diets’ and obesity as significant risk factors. These findings align with historical trends where the introduction of highly processed foods coincided with increasing cancer rates.
In many parts of Latin America, the Caribbean, and Asia, an uptick in colorectal cancer rates spans both younger and older populations. Hyuna Sung, a senior principal scientist at the American Cancer Society, notes that as regions develop economically, lifestyle changes often follow, potentially heightening cancer risks. ‘In countries that are growing, fast foods are considered a new trend,’ Sung explains, linking lifestyle shifts to increased cancer incidence.
While fast and ultra-processed foods are under scrutiny, experts caution that they are likely part of a broader range of contributing factors, including sedentary lifestyles and potential environmental exposures like forever chemicals. As physical activity decreases in industrialized settings, Giannakis and Sung emphasize the complexity of environmental influences on cancer trends.
In light of these findings, Sung and Giannakis advocate for proactive lifestyle changes rather than alarm. They emphasize the potential to reduce risk through healthier daily habits. Consuming whole foods, maintaining a healthy weight, reducing alcohol consumption, and quitting smoking are all recommended. Recognizing symptoms and seeking medical advice early could also provide opportunities for early intervention.
As colorectal cancer rates rise among younger populations worldwide, understanding and adapting to the factors behind this trend becomes increasingly urgent. While this research emphasizes dietary and lifestyle influences, it also highlights broader environmental and societal shifts that contribute to health outcomes. By making informed lifestyle choices now, younger generations can proactively address these challenges, reducing their risk of colorectal cancer and improving overall wellness.
