Purpose: To compare tumor size by mammography and sonography and align with pathological results in primary breast cancer cases. Materials and Methods: We retrospectively reviewed 95 primary breast cancer patients who underwent mammography and sonography from January 2011 to June 2012. The largest tumor diameter was chosen as sizing reference for each imaging modality. The measurements of mammography and sonography were considered concordant if they were within the measurement of pathological results ${\pm}0.5cm$. Pearson's correlation coefficient was calculated for imaging results. Results: The range of the maximum diameter was 0.6cm-10.5cm and mean value was $3.81{\pm}2.04cm$ by pathological results, 0.7cm-12.4 cm and $3.99{\pm}2.19cm$ by mammography, and 0.9cm-11.0cm and $3.63{\pm}2.01cm$ by sonography, respectively. Sonography (R: 0.754), underestimated tumor size, but had a better correlation with pathological tumor size compared to mammography (R: 0.676), which overestimated tumor size. Conclusions: Sonography is superior to mammography in assessment of primary breast cancer.
