Among 480 patients, BI-RADS scores were distributed as follows:
- 4A: 324 patients (67.5%)
- 4B: 81 patients (16.9%)
- 4C: 75 patients (15.6%)
Overall cancer incidence
- 16.88% (81/480) of BI-RADS 4 patients were diagnosed with breast cancer (invasive and DCIS).
Overal cancer rates by BI-RADS category
- 4A: 5.9%
- 4B: 21.3%
- 4C: 56.8%

KEY FINDINGS
- BI-RADS 4A and 4B categories were overused in elderly patients, potentially underestimating malignancy risk.
- Younger patients (<50 years) were frequently overclassified into BI-RADS 4C, leading to unnecessary biopsies and heightened anxiety.
- Triple-negative breast cancer (TNBC) was predominant in younger patients, with significant radiological features leading to 90% of cases classified as BI-RADS 4C.
