Distribution of tumour cell density within the tissue for decreasing p _i and costant${\mathit{k}}_{\mathit{i}}^{\mathbf{+}}$. 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. Parameter values p _N =0.5 and $k_i^{+}$ are 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 .
