Early-Onset Colon Cancer Rises in Argentina as Galicia’s Screening Finds More Tumors Early

The contrasting data points to organized testing as a practical way to catch disease sooner and curb its toll.

Overview

  • Sergas reports that by December 31, 2024, Galicia’s colorectal screening reached full coverage and found 298 cancers in 2024, with about two thirds at early stages.
  • Participation climbed to 56.51% in 2024 after mailed home stool kits began in 2022, with 66,232 follow-up colonoscopies since 2013 and nearly 26,500 people under lesion surveillance.
  • The program invites adults ages 50 to 69 to return a fecal immunochemical test, and a positive result leads to an offered colonoscopy to find or remove growths.
  • In Argentina, clinicians report a steady rise in cases in people under 50, now estimated at 10% to 15% of diagnoses, with lifestyle and environmental factors cited as possible drivers.
  • Specialists urge prompt checks for red flags such as blood in stool, lasting bowel changes, abdominal pain, or anemia, and they recommend starting routine colonoscopy around age 45 to 50 or earlier with a family history.
