Rising rates of colorectal cancer found in nearly all age groups

Colorectal cancer incidence rates are rising across nearly all age groups for the first time in over 20 years, extending beyond younger adults to those up to age 69, according to a study in NEJM Evidence. While increased screening among 45-49-year-olds explains some of the rise in that group, increases in older age groups suggest unknown risk factors are at play despite high screening rates. This trend has significant implications for healthcare systems facing growing demand for cancer treatment and survivorship care.
