Core needle breast biopsy

If cytologic puncture cannot yield adequate material for analysis, which actually happens in about 10-15% of the cases due to either the structure and consistency of the change or its location within the breast, a larger amount of tissue should be taken to obtain an accurate diagnosis. If, on the other hand, there is a raised suspicion that the process within the breast is malignant and advanced to the extent requiring early start of chemotherapy, a specimen of the abnormal tissue is taken for detailed pathohistological evaluation to determine the optimal combination of cytostatic chemotherapy agents. Core needle biopsy has therefore been used with increasing frequency to obtain such specimen and avoid more aggressive surgery. Core needle biopsy or biopsy that involves the use of a large-bore needle is performed under ultrasound guidance to obtain a tissue sample for pathohistological analysis. The complete biopsy results, given by eminent breast pathologists, can be obtained in only 5-6 days.
