Tumor Static Exposure curve for two different exposures. Both axes can represent plasma concentration of an anticancer drug, one axis can also represent radiation dose. All exposure pairs on the blue line result in the tumor being in stasis and thus, exposures below it (red area) lead to tumor growth while exposures above it (green area) lead to tumor shrinkage. The values on the axes are only chosen for illustrative purposes
