In this paper we develop an algorithm for the semi analytic solution of the Caputo-Fabrizio fractional order mathematical model for cancer treatment by stem cell and chemotherapy using Laplace Adomian decomposition method. The recursive iterative schemes for the model were solved using the model parameters and the given initial conditions, the result obtained is in good agreement with the one presented by Alqudah (2020) validating LADM's efficiency and accuracy in finding the approximate analytic solution of the Caputo Fabrizio fractional order mathematical model for cancer treatment by stem cell and chemotherapy.
