BI-RADS v2025 breast ultrasound: glandular tissue, non-mass lesions, and lymph node assessment updates

BI-RADS v2025 breast ultrasound updates refine glandular tissue descriptors, introduce structured non-mass lesion characterization, and standardize lymph node reporting, with emphasis on dense-breast screening in Asian populations.

• Review summarizes three main updates: glandular tissue component refinement, new terminology for non-mass lesions, and structured lymph node assessment.
• Highlights clinical implications for Asian settings where dense breasts are common and ultrasound is integral to screening and diagnostics.
• Narrative review without systematic methodology; discusses interpretation of official BI-RADS v2025 changes rather than providing new data.
