Computer aided diagnosis (CAD) systems can be used as a second opinion to the radiologists for diagnosis of breast cancer from mammogram images. In this paper, we have proposed preprocessing method to remove noise from mammogram images. Then, enhancement has been performed. After that, background has been removed. Finally, pectoral muscle separation has been performed. It has been noted that results are very much satisfactory. This can be used further to improve the accuracy of diagnosing breast mammogram. We have used MIAS data set for experimentation purpose.
Key words: Breast cancer, mammogram, enhancement, pectoral muscle.
