Role of Mammography Combined with Ultrasonography in Evaluation of Breast Lump

摘要

Breast cancer is one of the major health problems in the world. Specially, in developing countries like ours, it is a major problem as patients present late in hospital. Hence, early diagnosis is important to reduce morbidity and mortality due to breast cancer. Mammography and Ultrasonography are two important imaging techniques to detect breast pathology. This study has been done to evaluate the role of mammography independently and mammography combined with Ultrasonography to diagnose breast lesions. This study was a prospective study conducted in Radiology department of Manipal Teaching Hospital for a period of 18 months. Total of 91 patients of more than 30 years presenting with breast lump were included in study. Mammography was performed in all cases followed by Ultrasonography. Findings were noted according to Breast Imaging Reporting and Data System (BIRADS). FNAC was done for all lumps with or without USG guidance and correlated with imaging findings. Mean age is our study was 44 +/- 7.6 years. Maximum number of patients presenting with breast lump was in the age group of 41-50 years (52.7 %). Benign lump was seen in 74.7 % of patients and malignant lump was seen in 25.3 % of patients. Sensitivity and specificity of mammography in differentiating benign from malignant lesions were 90.9 % and 92.7 % respectively. Mammogram was inconclusive in 15.4 % of patients of age group less than 50 years. Sensitivity and specificity of mammography combined with USG increased to 95.65 % and 95.58 % respectively. Combined USG and mammography has high sensitivity and specificity in diagnosing breast lesions. Hence, these two imaging modalities should be combined for evaluating breast pathology, especially in younger patients with dense breast.
