DATA COLLECTION/INTERPRETATION: All data will be collected prospectively by the research staff or nursing staff (nursing staff at the WPCC will not be involved in research activities). Before the biopsy, a questionnaire will be completed by the patient to identify any factors that may influence pain perceived during the biopsy as well as baseline demographic information: age, race/ethnicity, education level, any analgesics taken the day of the biopsy. The physician performing the biopsy and indication for the biopsy will also be noted. The primary outcome of interest will be pain score on the visual analogue scale during lidocaine infiltration. A total of three pain scores will be obtained by the research assistant or nurse: A baseline pain score prior to intervention, pain score at time of infiltration, and pain score at the completion of the biopsy. This will be measured by asking the patient to mark her pain level on a 100 mm scale at each predetermined time point.
