ObjectiveThe purpose of this study was to evaluate the utility of core needle biopsy as a diagnostic tool for palpable breast lumps in developing countries as compared to fine needle aspiration cytology.Material And MethodAll patients attending the surgery outpatient department with palpable breast lumps were subjected to fine needle aspiration cytology and core needle biopsy by the same operator in a single session. Fine needle aspiration cytology was performed by the standard technique. Core needle biopsy was done freehand using a 14G manual core biopsy needle. Reporting categories of the two techniques were taken from the standard National Health Service Breast Screening Programme criteria and were compared with the final histopathology results.ResultsA total of 107 patients underwent fine needle aspiration cytology and core needle biopsy simultaneously. Histopathology was available for 85 cases. Statistical analysis of fine needle aspiration cytology and core needle biopsy showed no significant difference between the diagnoses offered by core needle biopsy and histopathology while there was a significant difference between fine needle aspiration cytology and histopathology diagnoses.ConclusionCore needle biopsy detected more breast carcinomas as compared to fine needle aspiration cytology with a sensitivity 95.83% as opposed to 64.58%. Though both the techniques were equally specific (100%), Core needle biopsy was able to correctly categorize borderline / inadequate lesions into definitely benign and malignant categories. We suggest that core needle biopsy should be preferred over fine needle aspiration cytology for the diagnosis of palpable breast lumps with fine needle aspiration cytology being reserved for definitely benign lesions.
