Recently availability of large scale mammography databases enable researchers to evaluates
advanced tumor detections applying deep convolution networks (DCN) to mammography
images which is one of the common used imaging modalities for early breast cancer. With the
recent advance of deep learning, the performance of tumor detection has been developed by a
great extent, especially using R-CNNs or Region convolution neural networks. This study
evaluates the performance of a simple faster R-CNN detector for mammography lesion
detection using a MIAS databases.
