Medical groups and a new study report that colorectal cancer incidence is increasing across multiple adult age groups in the United States, raising concern that risk factors beyond screening changes may be involved. The reports focus in particular on increases among younger adults, alongside continued rises in older groups.
Fast Company and the Medical Xpress brief confirm the study’s central finding: colorectal cancer rates rise across nearly all age groups, as published in NEJM Evidence. Fast Company adds specific figures, describing an increase in the age-adjusted incidence rate from 36.7 per 100,000 people in 2022 to 38.3 in 2023, and notes the sharpest increase among adults aged 45 to 49. It also emphasizes the screening context, including a recommendation shift to begin screening at 45, while pointing out that this does not fully explain rising rates among those aged 65 to 69. The Independent stresses the concern about an “invisible environmental threat,” while offering less methodological detail in the provided summary. Hacker News relays the same broad takeaway but provides only comments rather than new reporting details.
