We take into account the presence of inhibitors and establish the existence and uniqueness of solutions under suitable conditions on the inhibitors interaction and the tumor growth.engjournal articleopen accessModelos matematicosTumoresMatemáticas (Matemáticas)Oncología12 Matemáticas3201.01 Oncología
