Changes in the spatial distribution of all tumour cells$\left(\mathit{\sum }_{\mathit{j}\mathit{=}\mathit{0}}^{\mathit{N}}{\mathit{T}}_{\mathit{j}}\right)$within the tissue for decreasingp_iand costant$\left({\mathit{k}}_{\mathit{i}}^{\mathit{+}}\right)$. Plots showing detailed changes in the spatial distribution of all tumour cells $\sum _{j=0}^N{T}_j$ within the tissue over time in the case of immunoevasion. Parameter values p_N=0.5 and $\left(k_i^{+}=\text{constant}\right)$.
