The purpose of our study was to assess the cancer detection rate and positive predictive value (PPV) for incidentally detected abnormal axillary lymph nodes with negative mammography and subsequent breast ultrasound (US). We included 7039 screened patients (mean age, 52 y) from January 2012 to March 2015 with negative mammography and subsequent breast US results. In two patients with positive lymph nodes, neither were from breast malignancy. The calculated cancer detection rate, PPV for biopsy and axillary biopsy rate was 0.3 per 1000 axillary US, 14.3% and 0.2%. Cancer rates for patients with a family or personal operation history, with cancer history and with no family/operation/cancer history were 0%, 0.1% and 0.2%, respectively. Our results indicate that the cancer detection rate and PPV for US were too low to recommend routine axillary scanning including screening breast US in patients with negative mammography and subsequent breast US, especially with no history of any cancers.
