Mathematical modeling provides a unique means to simulate different cancer growth patterns. However, the current published models included only functional information, few of them considered the effect of environmental structure. In this study, we simulated the breast tumor growth in the duct by coupling tumor growth and duct wall deformation. By varying the key parameters, we could identify key mechanisms for DCIS to progress to invasive cancer. The simulation result is further correlated with the lesion phenotype shown on MRI. Understanding these biological growth patterns of DCIS may be further used to refine diagnostic criteria.
