US Colorectal Cancer Rates Rise for First Time in 20 Years

US colorectal cancer rates rose in 2023 for the first time in 20 years, according to an analysis of cancer data from 2000 to 2023.

The rate increased from 36.7 cases per 100,000 people in 2022 to 38.3 in 2023.

The increase is no longer limited to younger adults: rates rose in all age groups under 70, with the sharpest rise among people aged 45 to 49.

Rates also increased among people aged 65 to 69, while they levelled off among those aged 70 to 74.

Colorectal cancer rates had generally fallen for years even as cases among younger adults rose, making the latest overall increase a change in that pattern.

Researchers do not know what is causing the rise, but one theory is that people born during or after the 1960s may face higher risk than earlier generations did at the same age.

The findings call for more monitoring and investigation to understand the trend.
