Fig 20. Reduction of the protumor recruitment: Early administration of the treatment.

Simulation performed on the system (35a)–(35g), with (32)–(34). Evolution of the tumor mass μ₁ (plain, left axis), and of the immune strength ${\overline{\mu }}_c$ (dashed, right axis) for several values of the treatment dose q. The dash-dotted line represents the time at which the treatment starts.
