Colorectal Cancer Surges to No. 1 Cancer Killer Among Americans Under 50
A new American Cancer Society analysis finds colorectal cancer is now the leading cause of cancer deaths in Americans under 50, with rising incidence and mortality in younger adults and a birth-cohort effect suggesting generational risk changes. Early detection is crucial, as most under-50 cases are diagnosed at advanced stages, yet only about 37% of 45–49-year-olds are up to date with screening, despite ACS guidance to start screening at 45; expanding and increasing screening could prevent many deaths this cohort.
