In this paper we consider an interaction between a monoclonal tumor and the macrophages, which show a prey-predator structure. This model is analyzed with fuzzy initial values, where the concept of generalized differentiability is used. The graphical solutions for the problem show us interesting results comparing it with the differential equation model.
