Follow-Up After Positive Cologuard Test

A colonoscopy is absolutely necessary following your positive Cologuard test result, and should be scheduled within the next 3 months to minimize your risk of advanced colorectal cancer. 1

Why Your Positive Test Result Matters

Your Cologuard test detected abnormal DNA and/or blood in your stool sample, which could indicate the presence of:

  • Colorectal cancer
  • Precancerous polyps
  • Other abnormalities requiring medical attention

It's important to understand that Cologuard is a screening test, not a diagnostic test. The screening process is not complete until you undergo a colonoscopy to determine the cause of your positive result.

Timing Is Critical

Research shows that delaying colonoscopy after a positive stool test significantly increases risks:

  • Delays beyond 6 months are associated with higher risk of colorectal cancer 1
  • Delays beyond 9 months (270 days) significantly increase the risk of finding cancer (48% higher odds) 1
  • The risk continues to rise with longer delays 1

What to Expect During Colonoscopy

A colonoscopy is a procedure that:

  • Allows direct visualization of your entire colon
  • Can remove polyps during the same procedure
  • Is the gold standard for colorectal cancer detection
  • Usually takes 30-60 minutes to complete
  • Requires bowel preparation the day before

Common Concerns About Colonoscopy

Many patients have concerns about colonoscopy that can be addressed:

  • Fear of discomfort: Sedation is provided to ensure comfort during the procedure
  • Bowel preparation: While challenging, modern prep solutions are more tolerable than in the past
  • Time commitment: The procedure itself is relatively quick, though you'll need someone to drive you home
  • Travel concerns: If travel is required, please let us know so we can help coordinate care 2

Next Steps

  1. Our office will contact you within the next week to schedule your colonoscopy
  2. Once scheduled, you'll receive detailed instructions for bowel preparation
  3. Please arrange for someone to drive you home after the procedure
  4. Let us know if you have any questions or concerns about the procedure

Why This Is Important

Colorectal cancer is highly treatable when caught early. The five-year survival rate for localized colorectal cancer is over 90%, but drops significantly when diagnosed at later stages. Your prompt follow-up with colonoscopy gives you the best chance for early detection and treatment.
