Tumor regrowth after a low-intensity treatment.

<p>The graph shows the evolution through time iterations of the number of Differentiated Cancer Cells—DCCs (continuous red line) with g = 5 while the rest of the parameters were set to their standard values. A number of Cancer Stem Cells (CSCs) corresponding to 1% of the grid size is introduced from the beginning of the simulation (dashed green line). Between iterations 5000 and 6000 DCCs are killed with a probability of 1%. The bottom part shows snapshots of central sections of the multicellular system evolution corresponding to three different time iterations (Colors: Gray—healthy cells, Blue—DCCs, Red-enlarged size—CSCs).
