چکیده
Fine needle aspiration biopsy of breast lump is an accepted and established method to determine the nature of lump and it may play an important role when it is difficult to determine the nature of the breast lump by clinical examination. It has been shown that FNAB can reduce number of open breast biopsies. Study was done to assess utility of FNAC as the initial diagnostic tool in patients with breast lump, to define diagnostic criterion, to subcategorize lesions into specific entities, evaluate false negatives and false positives, to cytological grade infiltrating duct carcinoma – not otherwise specified (IDC-NOS) on the Robinson ’ s cytological criteria and correlate with histological grading based on Elston ’ s modified Blooms and Richardson method. Evaluating the efficacy of FNAB in surgical management and statistics. Prospective 2 year study of 334 patients was at a tertiary care hospital. A proforma was made for careful clinical examination of the breast lump. Patient was explained the procedure. FNA was done with 20-22G needle and 5-10cc syringe. Smears were fixed in 90% ethanol and stained H&E, PAP and Giemsa. Age of the patients was 11-90 years. Fibroadenoma was the most common benign lesion whereas IDC-NOS was the most common malignant lesion found. Cyto-histopathological correlation was found in 181 cases.
