They are microcalcifications, distortions, or nodules that are most commonly referred to as diagnostic category BIRADS 4. Depending on the multidisciplinary team and the facilities and resources of the treatment center, three types of instrumentation are in use, sometimes separately and sometimes in combination. The least invasive, least expensive, least resource intensive procedure is fine-needle aspiration cytology (FNAC), which is used attached to a stereotactic instrument, preferably with the patient lying prone.
1 When visualized on ultrasound, FNAC can be performed under direct guidance by the radiologist. To achieve a high true positive and true negative biopsy rate, study by a trained cytopatholgist is an absolute requirement. A disadvantage with FNAC is that a diagnosis of invasive cancer is not obtained, and only if the mammographic features are strongly consistent with malignancy can definitive surgery be recommended. …
