Rising rates of colorectal cancer found in nearly all age groups

A study by Caitlin C. Murphy and colleagues published in NEJM Evidence shows colorectal cancer incidence rising in most age groups in the United States, no longer confined to people under 50. The age-adjusted incidence rate was 55.2 per 100,000 in 2000, fell to 36.7 per 100,000 in 2022, and rebounded to 38.3 per 100,000 in 2023. Among people aged 45–49, incidence rose 12.76% annually from 2019 to 2023, the steepest increase.
