In this paper, two models are introduced based on cellular automata and the game theory to study behavior, growth, development and morphology of cancerous cells by assuming nutrition supplies, extracellular matrix, and immune cells. A two-dimensional cellular automaton combine with game theory is considered as the structure of model. The cellular automata modeling framework can be an efficient approach to a number of biological problems; and game theory aims to help us to understand situations in which decision-makers interact such as competitive activity. In the first model, we consider different oxygen supplies to study the growth and invasion of cancerous cell. The results of our simulation are validated by the results of other articles. The results show that the number of cancerous cells is easily changed by changing amount of oxygen supplies, but invasive distance of tumor cells is not easily affected by this factor. Furthermore the results of this model are not linear, that could show the improvement of the model. In addition, this model has the ability of producing metastasis, as it is shown. In the second model, the interaction between immune cells and cancerous cells are considered. Two-dimensional cellular automata and game theory are used for this purpose. In this model the behavior of cellular automata is determined by the game theory. The rules of cellular automata are determined by game theory table, so each element of the system could make a decision separately.
