Evaluation of breast cancer size is important for preoperative surgical planning and determining response to neoadjuvant chemotherapy. Due to the limitations of clinical breast examination, imaging assessment of tumor size is important. The purpose of this study is to compare preoperative breast cancer size as determined by mammography and sonography and correlate to pathologic size. In 117 invasive breast cancers, tumor size was measured mammographically and sonographically prior to surgery and correlated with postexcisional pathologic measurement by regression linear analysis. The tumor histologic type was considered in the correlations. Mammographic (r = 0.8585) and sonographic (r = 0.8701) measurements of tumor size correlated well with pathologic size. The correlation persisted when evaluating the differing histopathologic types of breast cancer and was greater for infiltrating lobular carcinoma than infiltrating ductal carcinoma. Both mammography and sonography can accurately measure tumor size preoperatively, regardless of breast cancer histopathology.
