We develop a field theory-inspired stochastic model for description of tumour
growth based on an analogy with an SI epidemic model, where the susceptible
individuals (S) would represent the healthy cells and the infected ones (I),
the cancer cells. From this model, we obtain a curve describing the tumour
volume as a function of time, which can be compared to available experimental
data.Comment: To appear in J. Appl. Math. Phys., 8 page
