Introduction:  One of the leading causes of cancer death in the less developed countries of the world is breast cancer. This is partly because of clinical advances to combat the disease which are not reaching the women living in those regions and also because of a shift in lifestyle, which is causing an increase in its incidence. All detected breast lesions are not malignant and all the benign masses do not progress to cancer; never-theless the precision of the final diagnosis can be greatly increased by radiological imaging (mammography, ultrasonography) and pathological diagnosis. Aims: To study the mammographic and ultrasonographic characteristics of breast lesions in patients, categorize the detected breast lesions according to BI-RADS, to correlate the categorized breast lesions (BI-RADS) with FNAC and compare the sensitivity of mammography with ultrasonography in diagnosing benign and malignant breast lesions. Materials and methos: This is a cross-sectional study completed during a period of one year in the DEPARTMENT OF RADIOLOGY,  KPC MEDICAL COLLEGE AND HOSPITAL, JADAVPUR. KOLKATA. Total 50 patients were included in this study. Result: All fat containing and low density lesions on mammography were benign on FNAC and the lesions which were of high density turned out to be either benign or malignant. Out of the total 16 FNAC proven malignant cases, the most common site was the central (retroareolar) region (5 cases). Commonest site was upper outer quadrant for benign lesions. All the oval lesions on mammography were benign except for one. Out of the 18 round lesions, 15 were found to be malignant. All lesions with spiculated margins and with fine pleomorphic type of calcification in mammography were found to be positive for malignancy in both mammography and on FNAC. All the oval shaped lesions on USG were proved to be benign on FNAC. All spiculated margin lesions in ultrasonography were found to be positive for malignancy on FNAC, while all the well circumscribed lesions were found to be benign. Conclusion: Combined USG and mammography yielded the best result and can be used as a screening modality to detect malignancy earlier and to treat the patient earlier.
