Bringing core biopsy into a surgical practice.

Minimally invasive diagnostic techniques in evaluating patients with breast disease have been increasingly utilized and accepted by physicians and patients over recent years. The incorporation of stereotactic core needle biopsy and ultrasound-guided core needle biopsy into the office practice of evaluating patients with breast disease by our surgical faculty has been met favorably. These procedures are readily learned by surgeons. The judicious use of these procedures is evidenced by the malignancy rate of core biopsies of 16 per cent, identical to the historical rate for needle localization assisted excisional biopsy at our institution. Core breast biopsy expedites definitive diagnosis and optimizes patient convenience. Reimbursement is highly variable, and active physician participation in negotiating with payors to insure that costs are met is essential.
