Tumor-host relationship: The viewpoint of an immunologist towards applied mathematicians

The assistance an immunologist with no claim to being strong in mathematics can provide is in the form of a definition of the basic elements of the tumor-host relationship as suggested by current thinking. This done, he can sit back in its immune Olympus, and look on as the applied mathematicians do their work. Yet he can also, like Homerʹs gods, streak in to stand beside them as they seek their way through the maze of models to bring his biological experience to bear and participate in the exploration of a new research area.
