In this paper a novel and application oriented mammogram segmentation using Nonlinear level set method and Radon Transform proposed. Handling medical images as a part of segmentation issues plays a critical phase. The proposed approach of nonlinear method of segmentation for which specific images of mammogram are consideredusing probability weighted force stopping function and Bayesian rules to extract the weak boundaries. This proposed method leads to get true extract boundaries and also
