A Comparative Study of Mammography and Sonomammography with FNAC Correlation in Evaluating Palpable Breast Masses

Abstract

Breast cancer is the most common cancer and the common cause of morbidity and mortality in women. Palpable lump requires appropriate evaluation, imaging and rule out malignancy. Mammography is the first line diagnostic imaging for evaluating breast lumps followed by high resolution sonography which additionally evaluates breast lesions and helps to characterize a mammographically non detected palpable abnormality in dense breast. An illustrated Breast Imaging Reporting And Data System (BIRADS) ultrasonographic lexicon was helpful in improving observer performance. So our objective isto evaluate the mammographic features and sonomammographic findings of the clinically palpable masses, to characterize the breast masses into benign and malignant based on mammographic and sonomammographic findings and to compare the categorized imaging findings with FNAC as a gold standard. This studywas done over a period from June 2016 to August 2018 and includes 100 patients. Women above 30 years of age, clinically had palpable breast lump were included in the study. Mammography and sonomammography findings according to BIRADS were correlated with cytological examination. Majority of the cases were benign. Fibroadenoma prevailed among the cases. For BIRADS I,II,III& younger population sonomammography was better. For BIRADS IV,V&older population mammography was better. Mammography & sonomammography cannot replace each other. Combined mammography and sonomammography were more accurate in evaluation of palpable breast masses.
