Introduction: International Academy of Cytology (IAC) has established a standardized approach for reporting Breast FNAC by categorizing the lesions in five tier system (C1 to C5) for diagnostic clarity, ultimately facilitating clinician?sunderstanding and use of FNAB cytology in Breast pathology. Material and Methods: Ours is a retrospective study done in the cytology section of the Department of Pathology GMC Jammu from January 2019 to January 2020. Results: A total 130 cases of Breast FNAC?s were included in the study with the maximum 111 (85.4%) females and 19 (14.6%) males. Maximum number of cases was seen in the age group of 31-40 years. CI (Insufficient/ Inadequate) lesions were found in 5 cases(3.84%), C2 (Benign) in 92 cases(70.76%), C3 (Atypical) in 8 cases(6.15%), C4 (Suspicious) in 6 cases(4.60%) and C5 (Malignant) in 21 cases(16.15%). Fibroadenoma was the commonest benign lesion found in our study in 44 cases out of 92 and Ductal Carcinoma was commonest among malignant lesions. Conclusion: FNAC is an essential component in the preoperative management of breast lesions and the IAC Yokohama system for reporting Breast FNAB cytology effectively stratifies breast lesions thus providing guidance to both cytopathologists and clinicians leading to better patient care.
