Early detection of breast cancer through mammography is crucial for successful treatment. Microcalcifications are small deposits of calcium in breast ducts, they can be an indication of breast cancer and are first detected by mammography. However, their presence must be confirmed by an histopathologist through slides examination. As a help to practitioners, we present an automatic microcalcification detection pipeline in Whole Slide Images (WSI). This pipeline is a patch-based approach, in which patches from epithelial regions are analyzed by a classifier to determine if they contain microcalcifications. We have developed two classifiers for this pipeline, one based on image processing techniques and the other on deep learning. In addition to standard classification metrics, we compare the performance of these two classifiers using custom metrics specifically designed to capture the value brought by the pipeline to pathologists. Both approaches provide promising results. The deep learning classifier has better metrics, but requires more labeled data to be implemented.
