  Article:   A STOCHASTIC MODEL FOR THE GROWTH OF CANCER TUMORS.

Authors:  HANNELORE LISEI, DAVID JULITZ.
 
       
         
  Abstract:  In this paper we study a stochastic model for the behavior of cancer tumors, described by a stochastic differential equation with multiplicative noise term. We consider that the number of tumor cells is influenced by the drug therapy and by random perturbations. We study the existence of the solution process, as well as its behavior in the framework of stochastic inclusion problems and random dynamical systems (long time behavior). Computer simulations are also given.
