Pain in different methods of breast biopsy: Emphasis on vacuum-assisted breast biopsy

This study examines pain (visual analog scale 0-10) in women undergoing breast biopsy. Two hundred and twenty-seven patients with a palpable lesion underwent FNA (21 G, n = 85), core biopsy (14 G, n = 86) or open biopsy under local anesthesia (17 = 56). One hundred and twenty-six women presented with a non-palpable lesion, and underwent vacuum-assisted breast biopsy (VABB, 11 G) under mammographic guidance, prone position (n = 72) or hook-wire localization followed by open surgery (it = 54). The techniques sampling non-palpable lesions were the most painful: hook-wire (9.15 +/- 0.74) and VABB (4.35 +/- 1.70). Larger needle diameter was associated with more intense pain. Concerning VABB, an S-shape curve of pain (third-order pattern) was documented. A second dose of lidocaine just before the rapid increase phase was then adopted (n = 61), and reduced the total/maximum pain. In conclusion, although VABB is less painful than hook-wire, the pain experienced in VABB is significant; however, it can be attenuated by a second dose of lidocaine. (C) 2007 Elsevier Ltd.
