Breast cancer is the most common malignancy among women worldwide, and early detection is crucial for improving patient outcomes [1,2]. The Breast Imaging Reporting and Data System (BI-RADS) standardizes malignancy risk assessment in breast ultrasound (BUS). However, the subjective nature of BI-RADS classification—particularly within the 4A-C subcategories—raises concerns about its reliability, especially in patients outside the standard screening age range (<50 and >70 years) [3].
This study aims to evaluate the limitations and potential misclassification within BI-RADS 4A-C in non-screening-age populations by:
- Assessing rates of over- and under-classification across different age groups.
- Comparing cancer incidence in BI-RADS 4A-C among young (<50), screening-age (50–69), and elderly (>70) populations [4].
- Investigating the impact of breast tissue density on diagnostic accuracy in non-screening populations.
- Highlighting potential clinical implications for patient management and risk communication [5].
