Diagnosis of non-palpable breast cancer: a review.

The literature on several methods of diagnosing non-palpable breast carcinoma has been reviewed. Skin projection and dye are methods not frequently used. Several aspects of FNA biopsy/cytology, ultrasound-directed methods, frozen section and MRI localization procedures are highlighted and comparisons are made. Much attention is being payed to needle localization breast biopsy and stereotactic core needle breast biopsy. The management of patients with mammographic abnormalities is shifting from needle localization to breast biopsy stereotactic core needle biopsy. Items of comparison between the two mentioned methods are accuracy, indications, complications and costs. The role of the ABBI system in the management of breast cancer has not yet been defined. A cooperative effort between the mammographer, surgeon and pathologist is critical to a successful image-guided breast biopsy programme.
