We take into account the presence of inhibitors and its interaction with the nutrients. We study the approximate controllability of the internal distribution of density of cells, that is proportional to concentration of nutrients, injecting inhibitor in a small inner region.engOn the mathematical controllability in a simple growth tumors model by the internal localized action of inhibitorsjournal articlehttp://www.sciencedirect.com/science/journal/14681218open access517.954Free boundary problemControllabilityGrowth of tumorsAnálisis matemático1202 Análisis y Análisis Funcional
