This analysis compares diagnostic accuracy and cost in breast cancer lymph node evaluation, suggesting benefits of core needle biopsy.

Prioritizing CNB as the first-line diagnostic approach could improve resource allocation in public healthcare systems, particularly in low- and middle-income countries where cost-effectiveness is crucial to expanding access to high-quality cancer care.
