In May 2018, the American Cancer Society updated its colorectal cancer (CRC) screening guidelines, lowering the age to initiate screening among average‐risk individuals from 50 years to 45 years because of increasing risk in younger generations and a favorable benefit‐to‐harm ratio. Herein, the authors report that past‐year CRC testing among individuals aged 45 to 49 years more than doubled during 2018 in concert with the Society lowering the recommended age for screening.
