Studying the correlation between the extracellular environment and the diffusion processes in tumor growth

The tumor behavior is understood as a complex dynamical system encountering many different scales. Following the principles of Jiang et.al, we also employ a multiscale model, where the environment of a tumor, at the extracellular level is described by reaction diffusion, while at the cellular level an agent based model is applied. We further extend this model by employing a health function, which describes at every time step the health state of any tumor cell. This health function takes into account the biological and biochemical micro environment. A stochastic function is applied to model the mitosis process of proliferating tumor cells.
