Abstract: Colorectal cancer is the most commonly diagnosed cancer leading to death in men and women. Computed tomography (CT) imaging technique established itself as the primary method for detection and staging in patients with colorectal cancer. In this work CT image of colorectal cancer are used to detect the area and staging the cancer. This work describes simple algorithm for pre-processing, clustering & post processing of CT images. This work uses image enhancement techniques and clustering using Fuzzy C-means algorithm which is implemented on MATLAB.
