Evaluation of Breast Masses using Ultrasonography

Abstract

Increased breast density is a risk factor for breast cancer and the sensitivity of detecting cancers in screening mammography in dense breasts is low. The use of ultrasonography in dense breast remains a controversial topic. The purpose of this study was to assess the usefulness of ultrasonography in evaluating of breast masses of women with or without family history of breast cancer, to evaluate the breast masses Echogenicity and texture, measure the size range, shape, and alignment of the breast masses, to evaluate the efficiency of ultrasound in diagnosing breast masses in order to reduce the mortality rate of the breast cancer. Mammogram was performed for 60 individuals with or without family history of breast cancer. Also all participants undergo ultrasonography for assessing breast masses. The breast ultrasound (US) examinations were performed by an expert radiologist in radial and anti-radial planes in a cross-sectional study. The data in this study were analyzed using SPSS version 21. From 60 subjects, there were 27 (45%) subjects diagnosed by ultrasound as Normal / benign, 19 (31.66%) subjects as probably benign this benignancy were approved by histology tests and none of them were malignant, 8 (13.33%) subjects as indeterminate on ultrasound and on histology only 2 (1.2%) were approved to be malignant, 2 (3.33%) subjects as probably malignant on ultrasound and approved by histology as malignant, and 4 (6.66%) subjects as malignant by ultrasound were approved by histology test as malignant . The results showed that ultrasonography is 100% sensitive in assessing breast masses than mammography. The sensitivity of mammography in the diagnosis of breast cancer is variable and influenced by age, breast density, family history, and other factors. Our data indicate that for the detection of breast cancer, sensitivity of US was greater than mammography in patients with dense breast.
