Tumors appear in various types and affect a huge variety of functional aspects. We focus on the stage when the cluster of cancerous cells becomes larger than the average diffusion length of the required nutrients. At this point the tumor starts to modify the surrounding vascular structure of healthy tissue which is a complex and not yet understood process. Since the changes in topology and spatial arrangement of blood vessels and capillaries affect the distribution of interstitial fluid, oxygen, etc. this process is of special interest in order to understand cancer at malignant scales.

We use computer simulations to design artificial blood vessel networks followed by modeling vascular tumor growth. During this talk I will give you a brief overview of our model.
