Abstract
Introduction: Breast carcinoma is the second leading cause of cancer related mortality in females around the world. Ultrasound plays a key role in differentiating cystic and solid lesions and is a convenient and non-invasive diagnostic tool to differentiate between benign and malignant lesions.
 Objectives: The aim of this study is to evaluate the diagnostic accuracy of ultrasound in palpable breast lesions.
 Methodology: A prospective cross-sectional study was carried out in patients with palpable breast lesions who presented in Department of radio diagnosis and imaging of Nobel Medical collegefor a period of one-year from February 2019- January 2020 using ultrasound. A total of 60 patientswereevaluated in the study. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated.
 Results: Out of 60 patients evaluated, ultrasound showed 46 (76.7%) cases to be benign and 14 (23.3%) cases to be malignant. FNAC revealed benign disease in 47 (78.3%) patients and malignant disease in 13 (21.7%) patients. The most common benign lesion was fibroadenoma. We found nearly 91.7% of the malignant lesions had spiculated margins and microcalcification. The sensitivity of ultrasound was 95.74% and specificity 92.3% with diagnostic accuracy 95%.
 Conclusion: Ultrasound is a convenient and non-invasive diagnostic tool with good sensitivity, specificity, positive predictive value, negative predictive value and accuracy in palpable breast lesions.
Highlights
Breast lesions are common in female pa ents than in male
Ultrasound has a key role in differen a ng cys c and solid masses. It has a useful role in the evalua on of palpable masses not visible in radiographically dense breasts; abscesses and masses that cannot not be completely evaluated with mammography as well as in young pa ents suscep ble to radia on damage.[6,7]
Mammography is known as the best screening test for breast cancer and has sensi vity of 85–95%; it can help in diagnosis of symptoma c or asymptoma c breast diseases.[8]
Summary
Pa ent present in advanced stage of disease due to lack of awareness and hesitant behavior of many females to reveal their illness. This leads to delay in detec on of the disease with worse prognosis especially in cases of malignancy, where the disease progresses to advanced stage, surgically inoperable, usually metastasize and eventually leads to mortality. Ultrasound is used as alterna ve modality with the advantage of being noninvasive and devoid of ionizing radia on
