A minimum standard for preoperative diagnosis of breast cancer of 70% has been set by the National Health Service Breast Screening Programme, (NHSBSP). Nationally, rates are 80% [BASO 1998-1999] and the rate in the southeast Thames region approaches 90%. Confirmation of malignancy by fine needle aspiration cytology or core biopsy avoids surgical biopsy, thus reducing the number of operations required for patients with breast cancer. We reviewed data from the regional breast screening QA database on 4402 cancers diagnosed in the years 1990 to 1999 of the NHSBSP in the southeast Thames region to measure the effect of a positive preoperative diagnosis (C5 cytology or B5 histology) on the number of operations required for treatment.
