Background: Breast lesions are the most common finding in females of all age groups but are most common in the reproductive age. Breast masses may appear suddenly or gradually. The presence of a breast lesion does not mean an individual has the cancerous disease because 11% of individuals present with breast lesions turned to have cancer of the breast. Pakistan is the seventh-most crowded state worldwide, is a nation in Asia.
Aim: To determine the diagnostic accuracy of ultrasound findings in the differentiation of benign and malignant breast lesions.
Methods: The Cross-sectional study was done to evaluate the diagnostic accuracy of ultrasound in 138 patients who visited the Radiology department and histopathology department Faisal hospital, Faisalabad between September 2019 and May 2020. Those who had breast abnormality on ultrasound were nominated for comparison with the histopathological finding taken from the tumors.
Results: The ultrasonographic features that most consistently characterize lesions are benign or malignant. Sonographically, 91 cases were classified as benign and 46 cases were malignant. 2 breast masses classified as benign on ultrasound were found to be malignant on biopsy. 6 breast masses classified as malignant on ultrasound were found to be benign on biopsy. So the sensitivity and specificity of ultrasonography were 96% and 93.81% respectively, and its negative predictive and positive predictive values were 97.85% and 88.89% respectively.
Conclusion: Diagnostic accuracy of ultrasound was 94.56%. Sonography could help in differentiation of benign and malignant lesions and can be following up.
