Tumour Spatial density in presence of immunoevasive mechanisms. Plots showing the distribution of tumour cell density within the tissue at times corresponding to 700, and 1100 days respectively. These plots illustrate the spatiotemporal onset of immunoevasion. The final plot at t=1100 should be compared to the equivalent plot in Figure 9, whereas the plot in the left panel, referring to time t=700 days, is analogous to the equivalent plot in Figure 9. These plots suggests that the onset of immunoevasion occurs after t=700days. Parameter values p _N =0.75 and $k_i^{+}=\text{constant}$. Solid line with chemorepellent, dashed line without. The red lines represent the population T₀, The blue lines represent the summed population T₁ + … + T _N , and the black lines represent the summed population T₀ + … + T _N .
