More Colorectal Cancer Diagnoses in People Under 55 Aren’t Only Because of More Colonoscopies

Colorectal cancer (CRC) is being diagnosed more often in the United States among adults younger than age 55. Does this mean more of them are getting colorectal cancer? Or are doctors finding it more often because more younger adults are having colonoscopies? In a study published in the Journal of Medical Screening, researchers at the American Cancer Society (ACS) found that colonoscopy trends don’t completely line up with the rates of colorectal cancer diagnosis by age, so more screening doesn’t fully explain the rise in CRC cases.
