Modelling cancer networks, with graph techniques, to be specific, use graph theory, such as network flow analysis, or web graphs to find where anomalies are, and predict the organs' behaviour are some of the areas where graph theory, can find use in. Other use of mathematical techniques, are those used in the field of knowledge management, knowledge discovery, and so on. Eigenvalues, with different measures show up bad genes from good, and could help in the isolation of cancerous areas. All this aids in the development of drugs that are used to cure cancer by studying their effects, on cancerous areas. For instance the web graphs could isolate and show up the drugs effects in time+cost effective ways.
