The International Academy of Cytology standardized reporting of breast fine-needle aspiration biopsy cytology: A 2 year's retrospective study with application of categories and their assessment for risk of malignancy.

FNAB is an important tool in the diagnosis and management of breast lesions, especially in financial constrained developing countries like India with limited resources, where practice of core needle biopsy is limited. The 5-tier IACYS for reporting breast FNAB improves the reproducibility of cytology reports across the world and helps in triaging the breast lesion patients.
