Repeating treatment (gray) controls the cancer population (red) while the fibroblast population (blue) gradually reduces. We simulate a mixed tumour of cancer cells and fibroblasts. Targeted therapy reduces the cancer cell population but not the fibroblasts. However, without stimulation, the fibroblast population declines naturally. Repeating treatment controls the cancer cell population, allowing the fibroblast population to revert to normal levels. After several treatments, the tumour regrows slowly, without flare.
