: The study has proved that breast cancer affects one out of every eight women in their lifetime. The early detection of abnormalities can reduce the risk factor up to large extent. Mammography is the effective strategy for screening breast cancer as small clusters of micro calcifications looks as white spots on mammograms showing early sign of breast cancer. The early detection depends upon the quality of mammograms and of course on the ability of radiologist's to read mammograms. The research paper focuses on the performing enhancement of poor quality images on the ROI (Region of Interest). The paper illustrates the procedure followed in enhancing the image via appropriate images.
