By considering the transformation τ = 2 D t from relation (2.4) and setting the diffusion coefficient D = 2 . 5 along with the number of glial cells C 0 / N 0 = 4 0 0 0 (as referenced in [11]), we obtain the values listed in Table 1. Using the numerical values in Table 1, Figure 2 is generated, showing the increase of the untreated tumour radius and the simultaneous decrease of the treated tumour radius over time.
