Previous studies have shown that colorectal cancer incidence is increasing among younger adults (aged <50 years) in multiple high-income western countries in contrast with stabilising or decreasing trends in incidence in older adults (aged ≥50 years).
The increase in early-onset colorectal cancer, previously seen predominately in high-income western countries, has now been documented in various economies and regions worldwide, marking it as a global phenomenon.
The global reach of this alarming trend calls for innovative tools to prevent and control cancers linked to nutritional attributes, physical inactivity, and excess bodyweight, which might be more challenging to address than the tobacco epidemic.
Educational efforts to increase awareness of the increase in the incidence of early-onset colorectal cancer and its unique symptoms, especially among primary care providers, would have far reaching effects in reducing delayed diagnoses and mortality.
