In this paper, we address the well-known Tumor-Immune Model of Kuznetsov
et al., converting it into a stochastic form, and for simulation purposes we employ
Euler-Maruyama discretization process. Such a modeling, for being realistic in
biology and medicine, requires the implication of memory components. We also explain
how to calculate the state transition time and we elaborate on how to reduce
the system dynamics after the state transition. In fact, we establish and evaluate
Stochastic Kuznetsov et al. model, and we describe how to demonstrate the stability
of the numerical method, addressing tumor growth in spleen of mice. This work
ends with a conclusion and a prospective view at future research and application,
with special focus on medicine and neuroscience of tumor analysis and treatment.
