Introduction: Worldwide breast cancer is the leading type of cancer in women accounting for 25% of all cases. In 2012, it resulted in 1.68 million cases and 5, 22,000 deaths. It is more common in developed countries and is more than 100 times more common in women than in men. Aims: To correlate cytological diagnosis with histopathological diagnosis of breast lesions, accuracy of FNAC in diagnosing breast lesions and the cytomorphology of various breast lesions of patients. Materials and Methods: The present study was a descriptive Cross Sectional study. This Study was conducted from March 2021 to November 2022, department of pathology at Darbhanga Medical College. Total 100 patients were included in this study. Result: On histopathology, Fibroadenoma was diagnosed in 54 cases, 20 cases were of infiltrating ductal carcinoma, 10 cases were Fibroadenoma with Fibrocystic change and 8 cases were fibrocystic change. There was one case of Borderline phyllodes, Adenosis with myoepithelial hyperplasia, Ductal Carcinoma insitu, Mucinous Carcinoma. Conclusion: Benign neoplasms of the breast are more common than malignant one.The present study shows FNAC correlation with histopathology with high specificity and maximum positive predictive value. However, FNAC can be used as an indicative diagnosis (one stop) for breast cancer examination in outpatient setting. Accuracy of FNAC enables to proceed with surgery or not. It bridges the gap between clinical evaluation and final surgical pathological diagnosis in majority of cases. It enables the clinician to obtain a diagnosis in high percentage of cases with minimal expenditure of time, amd money and often to avoid unnecessary surgery. |
