Abstract

Lévy theory provides a potential mathematical framework to model space and space-time stochastic processes. In addition, spatial point processes define stochastic models for random patterns of points in These processes play a special role in stochastic geometry as the building blocks of more complicated random set models. In this paper, we focus on a family of Lévy-based spatial Cox processes to model and predict tumor growth. We develop a procedure to simulate the growing of tumors. This algorithm can be used to study the evolution in time of any 2- and 3-dimensional geometrical forms such as cancer skin and all type of boundary evolution. We analyze real data and show that the procedure developed works fine and is useful for prediction purposes.
