Background: Breast lesions commonly present as palpable breast lumps. FNAC is a first line, minimally invasive and cost-effective investigation in diagnosis of breast lumps with high levels of accuracy in differentiating various benign and malignant. Aims and Objectives: The aim is to study the spectrum and distribution of breast lesions according to IAC Yokohama system of reporting breast cytopathology. Materials and methods: This is a retrospective study conducted in the Department of Pathology in Government Medical College Rajouri over a period of one year from January 2021 to January 2022.Results: Out of 134 cases, majority of the cases were in category 2 i.e.,70.9%. most common benign lesion is fibroadenoma i.e., 48.42% of all the benign lesions.Category5 has 11.94% of the total cases. Most common malignancy is ductal cell carcinoma i.e., 87.5% of the total malignancies.Conclusion: Categorization of the lesions according to the IAC Yokohama system of reporting breast cytopathology gives uniformity to the results by different cytopathologists. Therefore, the management can be planned by the surgeon according to the risk and unnecessary delay can be prevented.
