Some real-world problems have complicated behaviors, so in the last twoyears, piecewise calculus has been developed to more accurately depict these issues. Thispaper will elaborate on and examine cancer tumor’s chaotic model from determinism torandomness. Several scenarios are considered. The existence and the uniqueness of thesolutions of the system are proved via Mao’s theorem. Graphics of numerical schemesand their numerical simulations.
