During breast cancer malignancy grading the main problem that has direct influence on the classification is imbalanced number of cases of the malignancy classes. This poses a challenge for pattern recognition algorithms and leads to a significant decrease of the classification accuracy for the minority class. In this paper we present an approach which ameliorates such a problem. We describe and compare several state of the art methods, that are based on the oversampling approach, i.e. introduction of artificial objects into the dataset to eliminate the disproportion among classes. We also describe the automatic thresholding and fuzzy c-means algorithms used for the nuclei segmentation from fine needle aspirates. Based on the segmented images a set of 15 feattures used for classification process was extracted.
