A model of a tumor cord cell population is analyzed in which individual cells are distinguished by cell age and radial position. The existence and asymptotic behavior of solutions are investigated. It is proved that solutions are asymptotically eventually periodic.
Keywords: nonlinear rst order partial di erential equation, asymptotic behavior., Tumor cord cell population.
