Ricci flow is an analytic surgery. Prediction and control of cancer invasion Can be done by Ricci flow theory see this paper

We can apply discrete Ricci flow like Ollivier Ricci flow, to study cancer and tumors

There are a list of discrete Ricci curvatures which based on we can define Ricci flow. Just we need to know which discrete Ricci curvature on the graph network is suitable for the tumor.
