There are 13% of women with BIRADS III and BIRADS IV ultrasound results, the rate of BIRADS III and IV in urban areas is 2.88 times higher than in rural areas (p<0.001). The logistic multivariate regression model tests some factors related to results of breast ultrasound in women are family history of breast cancer (OR = 6.04; 95% CI 1.47 – 24.77; p=0.012) and have a benign tumor (OR = 2.94; 95% CI 1.46 – 5.88; p=0.002).
