Colorectal cancer rates in the United States rose again, from 36.7 per 100,000 people in 2022 to 38.3 in 2023, after declining for more than two decades. Among adults aged 20 to 49, cases increased by 3% annually from 2013 to 2022, and by 2026 the disease had become the leading cause of cancer death in this age group. The largest annual increase—12.76%—was recorded among people aged 45 to 49, partly following the lowering of the recommended screening age to 45. But expanded screening does not explain the increase across all age groups. Meanwhile, tumor samples from younger patients showed greater activity of molecules that may regulate genes, as well as of signals between cells that could contribute to cancer spread.
