Colorectal Cancer Cases Rising in Younger Adults, Linked to More Screenings

More younger adults are being diagnosed with colorectal cancer, and new research suggests that a major reason may be increased screening among that age group.

Two new studies from the American Cancer Society point to a possible connection between rising diagnoses and a recent surge in screenings among adults ages 45 to 49. Until recently, the recommended age to begin screening for colorectal cancer was 50, but that guideline has been lowered to 45 in response to concerning trends in early-onset cases.

In one of the studies, researchers found that in 2023, nearly 34% of adults between ages 45 and 49 were up to date on their colorectal cancer screenings. That marks a significant jump from just a few years prior, when only around 21% of people in that age group were current on their screenings.

Experts say the increase in screenings may be helping detect more cases earlier, which can be critical for improving outcomes. However, the data also underscores the importance of continuing to raise awareness about early-onset colorectal cancer and ensuring access to screening options for younger adults.
