Using game theory to understand the physics of cancer propagation

In the context of cancer, cooperator cells obey the general rules of communal survival, while cheater cells do not.

The ultimate goal of this research was to gain an understanding of the dynamics of cancer tumor evolution under stress. Since cancer can be likened to a community of bacteria, the researchers zeroed in on a simple bacterial model to examine the progression of resistance to drugs under high competition and stress conditions.

Among their key findings: they discovered emergent cooperative outcomes between the two cell types after modifying their game theory framework to account for heterogeneous stress patterns.
