Background: Aim to compare and assess cytomorphological grading systems of Breast malignancy with that of histological grading system. Materials and Methods: 63 cases of Breast malignancies were included in the present study. Fine Needle aspiration smears stained were perused and allocated gradings by two pathologists independently. Results of 5 grading systems were compared with that of Nottingham modification of SRB histopathological grading system. Results: The spearman’s rank order correlation coefficient show statistically significant values for Moriquands, Khan, Taniguchi and Robinson. It shows a strong R value of 0.64787 for Moriquands followed by R value of 0.5404 for Robinsons. R value of Khan is 0.39467 which is not statistically significant. High concordance rate was observed for Moriquands. Conclusion: In our study except for SRB all the other four cytological grading systems were equated with histopathological grading system, hence cytological grading should be incorporated in the cytological reporting of breast cancers to decide the strategy of the treatment
