A STUDY ON FINE NEEDLE ASPIRATION CYTOLOGY OF BREAST LESIONS ACCORDING TO IAC YOKOHOMA CLASSIFICATION AND ITS HISTOPATHOLOGICAL CORRELATION, AT TERTIARY CARE HOSPITAL, GHAZIABAD

Breast lumps are a frequent concern among women and often present with symptoms such as pain, palpable masses, or nipple discharge. These symptoms can lead to considerable anxiety, though most breast lumps are benign. Fine Needle Aspiration Cytology (FNAC) offers a rapid, minimally invasive, and cost-effective diagnostic approach that helps differentiate between cystic and solid lesions and plays a crucial role in identifying malignancies. This study, conducted at the Pathology Department of Santosh Medical College, Ghaziabad, aimed to assess the cytomorphological patterns of breast lesions using FNAC, evaluate its diagnostic accuracy, and correlate findings with histopathological results using the IAC Yokohama classification. Over a year, 258 patients underwent FNAC, with histopathological follow-up available for 136 cases. FNAC showed high diagnostic performance, with a sensitivity of 92.86%, specificity of 100%, and overall accuracy of 93.8%. The majority of cases were benign (C2), and most lesions measured between 2–5 cm. These findings reinforce FNAC’s critical role in the early, accurate, and reliable preoperative assessment of breast lesions.
