  • Abstract

We present an iterative method to numerically simulate the growth and shrinkage of tumor. We transformthe free boundary problemdescribing tumor growth into the boundary integral equations which reduce the dimensionality of the problem by one. By boundary element method, we discretize the boundary integral equations by grid points on the moving boundaries of tumor. We estimate the error of the numerical integration. We design an iterative scheme and implement successfully this scheme to visually and graphically show the evolution of the interface between the tumor and the external tissue at differentmoments of time. In this paper, the proliferation rate μ is a function of space x and time t. Our numerical method professor Bei Hu proposed is novel and our numerical results are in agreement with the tumor growth in vivo.
