Fine needle aspiration biopsy (FNAB) of breast lumps: comparison study between pre- and post-operative histological diagnosis

Fine-needle aspiration biopsy is recommended as first and most important step in the management of breast cancer. A retrospective study was realized on 420 patients that underwent fine-needle aspiration (FNAB) in comparison to 140 patients that underwent surgical management. The results of FNAB showed that 81% of the cases were benign with an accuracy of 93%, a specificity of 97% and a sensitivity of 92% compared to operative findings. The accuracy of FNAB depends on the expertise and experience of the cyto pathologist as well as the technical skills of the physician performing the biopsy. FNAB is showing to be a highly effective procedure which can obviate unnecessary surgery in breast suspected lumps, save time and money and patient anxiety. It is the effective method for distinguishing benign from malign breast lesions.
