A hyperbolic tumor growth model with Robin free boundary is studied
which contains an elliptic partial differential equation describing the concentration of nutrients
an ordinary differential equat
ion describing the radius of tumor and two hyperbolic equations describing the growth of tumor cells. In this paper
by applying the method of characteristic curves and the Banach fixed point theorem
the existence and uniqueness of the global solution of the model are proven. Finally
it is proven that while
${K_R} = 0$
