AI Summary (NQ-processed)
A National Taiwan University (NTU) research team analyzed data from nearly 4 million colorectal cancer screenings and found that individuals with higher fecal hemoglobin levels face a 1.7-fold higher risk of developing colorectal cancer even after polyp removal, confirming fecal hemoglobin concentration as a key factor in determining colonoscopy follow-up intervals.

Frequently Asked Questions
- Q: What should I do if my fecal hemoglobin is high?
- A: A high level doesn't mean cancer, but consult your doctor for earlier or more frequent colonoscopy.
- Q: When to rescreen after polyp removal?
- A: Low-risk: 7–10 years; high-risk: 3 years. Fecal hemoglobin can refine timing.
- Q: Is annual colonoscopy necessary?
- A: No. Over-screening increases burden. Follow risk-based intervals.
