How often should a 10mm hyperplastic polyp in the colon be screened again?

1. 5 years

2. 10 years

3. 15 years

4. 20 years

The correct answer is: 10 years

For a 10mm hyperplastic polyp in the colon, the recommended screening interval is 10 years. The guidelines suggest that hyperplastic polyps, especially those less than 10mm, are generally considered to have low malignant potential. However, the size of the polyp plays a crucial role in determining the follow-up screening frequency. When dealing with polyps, the risk of progression to colorectal cancer must be weighed against the need for surveillance. Larger hyperplastic polyps may warrant closer monitoring, such as a follow-up colonoscopy in 10 years, rather than the longer intervals recommended for smaller hyperplastic polyps or adenomatous polyps. This 10-year recommendation is grounded in evidence and established guidelines for colorectal cancer screening, which address the nature of such polyps and their associated risks. Larger polyps, particularly those around 10mm, indicate a need for more diligent follow-up to ensure that any potential concerns are identified in a timely manner and that the goal of preventing colorectal cancer is thoroughly addressed.
