What are the limitations of current screening methods?
While current screening methods are effective, they have limitations:
1. False Positives/Negatives: No screening method is perfect. False positives can cause unnecessary anxiety, while false negatives can delay crucial treatment. 2. Availability: Not all screening tests are available in all regions, which can lead to disparities in early detection. 3. Cost: Some advanced screening methods can be expensive, limiting access for some families.
