Colorectal cancer rates are falling among older adults, largely because of increased screening. But researchers are seeing a troubling shift in younger people, with more cases now appearing in adults under 50, including some in their thirties. A new nationwide study from Switzerland found that diagnoses in this age group have been steadily rising for decades, while younger patients are also more likely to receive a late-stage diagnosis.
The research was led by scientists from the University of Geneva (UNIGE) and the Geneva University Hospitals (HUG). Published in the European Journal of Cancer, the study analyzed nearly 100,000 colorectal cancer cases recorded in Switzerland over a 40 year period. The findings point to a growing public health concern and highlight the need for greater awareness of early warning signs.
Colorectal Cancer Rates Rising in Younger Adults
Colorectal cancer is currently the third most commonly diagnosed cancer worldwide and the second leading cause of cancer deaths. According to the World Health Organization, more than 1.9 million new cases were reported globally in 2022, resulting in nearly 900,000 deaths.
The highest rates of colorectal cancer are seen in Europe, Australia, and New Zealand, while Eastern Europe has the highest death rates linked to the disease.
