Abstract: In this paper, we employ the Residual Power Series Method (RPSM) to derive an approximate computational solution for a mathematical model of cancer tumors. Our study specifically examines the effects of chemotherapy on cancer, investigating the interactions among chemotherapeutic agents, tumor cells, normal cells, and immune cells within the framework of fractional partial differential equations (FPDEs). The RPSM is utilized to deliver highly accurate solutions in the form of series with rapid convergence, even for nonlinear and complex models. Mathematical modeling is essential for exploring hypotheses related to biological phenomena, particularly in recent decades, where significant advancements have been made in predicting chemotherapy outcomes through the modeling of tumor-immune system interactions. In this research, we analyze the impact of cancer tumors through a system of FPDEs defined by the Caputo derivative. We present two- and three-dimensional graphs to illustrate the relationships between various parameters and variables, thereby demonstrating the effects of chemotherapy on cellular dynamics.
