Cancer Detection using Image Based Computer Aided Diagnosis System

This paper overviews one of the most problems in cancer diagnosis process. This study zone major causes of non-accidental death in human. Cancer is a type of disease in which a group of cells exhibits irregular cell growth cycle. In a normal cell cycle, the cells undergo mitosis process to replicate itself and hence the cell grows. The cancer cell can also migrate to other parts of body by the bloodstream or lymphatic system. In cancer, the cells lost such balance and grow uncontrollably, to form malignant tumors invading the surrounding tissues. In an existing system clinician visually examine the medical images to identify the cancer based on their experience. There is a difficulty to identify the cancer in complex image. The result may have the less accuracy. To overcome the drawbacks of an existing system developing an effective image based Computer Aided Diagnosis (CAD) system to assist clinician in diagnosis process.
