Towards this, mammography is the main diagnostic test for screening of breast tumors wherein high quality images with low dose x-rays are used to image the breast(s). Due to the immense danger that this disease presents it becomes necessary to develop a Computer-aided diagnosis (CAD) systems to improve radiologistís diagnosis. This paper has implemented such a system. The developed method proceeds in four steps: pre-processing mammograms for enhancement, segmentation to detect breast abnormalities, then texture feature(s) are extracted and finally image is classified.
