- Minimally invasive, low cost, can be performed under
mammographic guidance
- 95% Specificity (radical mastectomy only after definitive
histology from a sample obtained with a core-needle, incisional or
excisional biopsy)
- 85% Sensibility (the benign diagnostic needs
definitive histology confirmation)
- Aspiration may resolve a simple cyst or establish an
unequivocally benign tissue diagnosis, obviating the need for further
evaluation
- Equivocal cytologic readings (eg. acellular, blood only, normal
fat or mammary cells) require further workup (generally formal biopsy).
