Background/Aim: To evaluate the usefulness and safety of vacuum-assisted breast biopsy (VABB) for breast lesion diagnosis and treatment. Patients and Methods: Clinical and histopathological data of 8,748 patients, who underwent 11,221 VABB procedures were analyzed. Results: Most patients (58.2%) were <40 years old. Most lesions (39.6%) were 0.6-1.0 cm in diameter while 3.2% were ≥3.0 cm; fibroadenomas were the most common (46.6%). Eight (14% of 57) cases of atypical ductal hyperplasia were underestimated. The positive predictive values (PPVs) of breast imaging reporting and data system (BI-RADS) ultrasound category were 0.6%, 3.4%, 34.8%, 66.2%, and 93.8% for category 3, 4a, 4b, 4c, and 5 lesions, respectively. The mean number of core specimens was 9.5±8.8; the mean procedure time was 3.4±2.7 min. No residual lesions were found in 94.4% of the 7,480 patients. Conclusion: VABB could replace ultrasound-guided core biopsy and surgical excisional biopsy for the diagnosis of breast disease and the treatment of benign breast lesions.
