Introduction: Breast cancer is the most common cancer in women throughout the globe, and the modern therapeutic available options have been widely researched currently. For a developing nation with limited resources, such as Pakistan, a quick, affordable, and least invasive technique like FNAC may give useful information.

Aim: The aim of this study was;

1    Perform and evaluate cytomorphological classification of all breast cancer patients using the Robinson's three-tier grading system.

2    Histopathological evaluation and classification of all samples of MRM by using a modified BR classification system.

3    Correlation of histo-morphological and cytomorphological classification systems.

Place and Duration: In the Pathology department of Khyber Teaching Hospital Peshawar for six months duration from February 2018 to July 2018.

Material and methods: A prospective study was conducted in which two independent observers classified all breast cancer patients on the basis of cytology and histology of the tissue and cyto-histological correlation.

Results: This study provided good individual correlation and inter-observer agreement in the cytopathological classification of breast cancer aspirates.

Conclusion: Cytopathological classification may be useful for these patients and should therefore be included in routine reports.
