Real-time colorectal cancer rates are increasing significantly among adults under 50, prompting urgent calls for earlier screening and awareness.

The American Cancer Society projects approximately 107,000 new colon cancer cases and 47,000 rectal cancer cases in the United States for 2025, with slightly higher rates in males. While overall colorectal cancer rates declined by 1% annually between 2012-2021, cases among those under 50 increased by over 2% yearly during the same period.

Recent cases highlight this concerning trend:

  • Sydney Stoner was diagnosed with stage 4 colon cancer at age 27 after initially having her symptoms dismissed
  • Angelica McFall discovered stage 3 colon cancer at 48 during her first colonoscopy, despite having no symptoms or family history
  • William Lindley learned he had stage 4 colon cancer at 38 after mistaking symptoms for IBS

Current Screening Guidelines:

  • Begin regular screenings at age 45
  • Earlier screening for those with family history or conditions like IBD
  • Standard interval is every 10 years for those without risk factors

Available Screening Methods:

  1. Colonoscopy (gold standard)

    • Most accurate detection method
    • Allows immediate polyp removal
    • Required every 10 years
  2. Alternative Tests:

    • Annual stool tests
    • CT scans
    • FDA-approved blood test (as of 2024)

Key Symptoms to Watch For:

  • Change in bowel habits
  • Diarrhea or constipation
  • Blood in stool
  • Abdominal cramping
  • Unexplained weight loss

Treatment Options:

  • Surgery
  • Chemotherapy
  • Targeted drug therapy

Medical experts emphasize that colorectal cancer is highly treatable when caught early, making regular screening crucial. Anyone experiencing persistent gastrointestinal symptoms should seek medical attention, regardless of age.
