Early diagnosis of breast lesions is indispensable, as this significantly decreases morbidity and mortality. Triple assessment (physical examination, radiology, and pathological examination-FNAC/core biopsy) is widely used for accurately diagnosing palpable breast lesions.

Correlation of BI-RADS with cytopathology included concordant malignant (83.33%) and benign (98.8%) cases, discordant malignant (16.67%) and benign (1.2%) cases, sensitivity (83.33%), specificity (98.8%), positive predictive value (96.2%), negative predictive value (94.4%), accuracy (94.8%), concordance (94.8%) and discordance rate (5.2%) were tabulated. 6/116 cases were discordant.</span></p> <p><strong><span>Conclusion:</span></strong><span> Detailed understanding with a robust multidisciplinary approach is required for definitive diagnosis, effective implementation of ameliorative strategies and long-term follow-up of patients.
