Background:Core needle biopsy is a gold standard for the diagnosis of breast lumps. Sometimes it is difficult for patients to afford its cost, especially in low- resource settings. Tissue processing is also not available at all hospitals and with all pathologists.We try to find out the concordance of MMSI (Modified Masood Scoring) in FNAC with histology and its utility in making better diagnoses thereby we can use it as a diagnostic procedure for malignant lesions in a low resource setting.Method: All patients with clinically palpable breast lumps referred to the Pathology department for fine - needle aspiration cytology (FNAC) were included. The patient was thoroughly informed and after taking consent, FNAC was done from 3 sites. These specimens’ lesions are also evaluated by applying Modified Masood’s Scoring Index (MMSI) and to access its usefulness in breast cytology also correlate with Histopathology.Results: The 89.52% and 98.15% of histological findings were correlated with MMSI category II and MMSI categories IV respectively. On applying the chi-square test, it is found to be highly significantly associated(p<0.001). Conclusion: MMSI gives a good prediction of the identification of breast lesions so one can plan effective management planning in low resource settings when the availability and affordability of core needle biopsy facility are not available.
