Figure 9.

Numerical solution of the model including proteases (solid blue line) is contrasted with the solution of the model without proteases (dashed black line). The area in between is shaded in cyan to highlight the difference. Parameters values are representative of a slow-growing tumor (γ = 0.01, ρ = 0.2, v = 0.01, and α = 0.4). We present snapshots at (a) an early time and (b) an intermediate time. (c) Shown is the corresponding heat map of pressure in a slow-growing tumor that is secreting proteases.
