RT Journal Article T1 On a simple model of tumor growth A1 Díaz Díaz, Jesús Ildefonso A1 Tello Del Castillo, José Ignacio AB We study a simple mathematical model for the growth of spherical tumors with two free boundaries: an inner boundary delaying the necrotic zone and the outer boundary delaying the tumor. We take into account the presence of inhibitors and establish the existence and uniqueness of solutions under suitable conditions on the inhibitors interaction and the tumor growth.
