This study analyzed updated SEER (Surveillance, Epidemiology, and End Results) database trends in early-onset colorectal cancer (CRC) incidence in the United States, with data extended through 2023, focusing on adults under 50 years of age.
The analysis found an accelerating rise in early-onset CRC incidence in the United States through 2023, though specific incidence rates and percentage increases are not available from the provided abstract alone.
As a SEER database study, findings are limited by the completeness and accuracy of registry data; causative factors driving the rise cannot be determined from incidence trends alone.
Clinicians should be aware of the accelerating upward trend in CRC among younger adults and maintain a low threshold for investigation in patients under 50 presenting with colorectal symptoms. This trend may support re-evaluating screening start ages in clinical guidelines.
