The research aims to design a system that cuts the cancerous area in the esophageal tissue that is often detected in late stages, using the FCM algorithm. This algorithm has achieved impressive results in determining the tumour area, which is; (sensitivity of 0.98, Accuracy of 0.95, and specificity of 0.92). The proposed system was tested on 200 images, which were downloaded from the Kaggle website. This research showed that is not possible to improve the images before using them in segmentation, due to the type of noise experienced by the data set is not uniform, because the images uploaded to the mentioned site are in JPG format (compressed images), which are losing many their features.
