COMPUTER AIDED DIAGNOSIS SYSTEM FOR BREAST CANCER DETECTION

Breast cancer is the most common cancer which affects women around the world. Breast cancer arises due to uncontrollable nature of breast cells which produces breast tumor. Cancer can be cured or prevented when only it has been detected at early stages. Detection and diagnosis is the main factor for breast cancer control which increases the success rate of treatment, saves lives and reduce the cost. Early detection of breast cancer is important for successful treatment. Digital mammography is a reliable method to detect breast cancer at the early stages. Further, X-ray mammogram is the most effective and economical breast imaging modality. The Computer Aided Diagnosis (CAD) system approach for breast cancer detection in mammogram breast images is presented. It consists of four step by step procedures namely preprocessing of breast images, image enhancement, feature extraction and classification. The CAD system not only provides second medical opinion for radiologist but also accelerates the process of detection.
