Continual increasing of breast cancer in young women, its rare discovery in the early stage (stage I), as well as high mortality from this disease, are the facts that explain why the breast cancer is a target for many scientists. Thanks to the Greek scientist Papanicolaou and his report (l928), a successful battle with the most frequent carcinoma in women - PVU carcinoma, has begun.
    With the development of exfoliative, brushing and fine needle aspiration cytological methods, the impressive results have been achieved. While cytologic methods are used more and more in the breast oncopathology worldwide, up to this moment their applications have been rare in our country, which is one more reason for this study reason more for this study.
    By using the exfoliative and fine needle aspiration cytology, 50 patients were examined. The following cells were discovered: foamy macrophages, lipoprotein background, mastitis, eritrocytes, ductal tumorous papilles, apocrine metaplasia and ductal carcinomas. Furthermore, cytological caracteristics of the breast cancers and both advantages and limitations of the cytologic methods were pointed out. It was concluded that, using cytological methods, discovery of both precancerous breast lesions and breast cancer was possible in the earli stage. Also, sufficient knowledge of histopathology was necessary for correct interpretation of cytological results because of frequent mimicry in oncologic pathology.
