Introduction: In females breast cancer is the second most common cancer in India with an incidence of 25.8 per 1,00,000 individuals. Most of the patients present with breast lump. Many due to lack of awareness present very late with advanced stage. Hence it is very important to diagnose the condition early with a proper screening modality. Materials and Methods: A prospective study was conducted on 100 women presenting with breast lump. All patients underwent mammography followed by histopathological assessment of the lump. Results: Irregular shape with ill defined borders on mammography was found to be significant marker of malignancy. Calcification in malignancy was 55.22 times more common than benign. The sensitivity of mammography was 84.62% and specificity of 80% with diagnostic accuracy of 83%. Conclusion: Mammography was found to be a reliable modality in diagnosing breast malignancy and hence concluding that it can be used as a diagnostic tool in breast lumps.
