This paper presents a cancer model that describes the interactions between two different kinds of cancer cells. Additionally, a sensitivity analysis is conducted to identify and compare the effects of specific alterations to the model's parameters. Furthermore, the model's behavior is assessed by taking into account the most significant parameters, as indicated by the sensitivity analysis, which identifies the convexity parameter as the key factor. Furthermore, we suggest a therapeutic approach utilizing replicator dynamics through an anti-coordination game that relies on densities, resulting in a reduction of the ultimate cancer cell population.
