    A simple discrete model for the growth tumor
    (Selcuk University Research Center of Applied Mathematics, 2009) Barrea, Andrés; Turner, Cristina
    In this work we propose a discrete model for the growth tumor. This model is based on the continuous model in [1] which uses the conventional ideas of nutrient diffusion and consumption by the cells. We assume that region is two-dimensional and we discretize by means of a grid NxN where sites are occupied by the different types of tumor cells (proliferating, quiescent and dead) and normal cells. The growth rules are stochastic and depend on the concentration of nutrient. A discussion of the results and applications of the model are presented.
