Optimal strategy for glucose injection for second surgery after attracting invasive cells via chemotaxis. (A–D) Growth patterns at final time (t = 33 h) for various glucose injection time $\left(t_1^G=10\left(A\right),12\left(B\right),15\left(C\right),17h\left(D\right)\right).$ Domain size = [0.2, 0.8] × [0.2, 0.8] ⊂ [0, 1]². (E) Tumor population for different $t_1^G.$ Tumor population is decreased as $t_1^G$ is increased due to delay of growth signal. (F) Resection area for second surgery for various $t_1^G.$ Resection area is decreased as injection time is increased.
