Metastasis Modelling Approaches—Comparison of Ideas

Modelling of cancer growth with metastasis can be approached in different ways. The aim of this work is to compare two model types to answer a question of their equivalence and applicability. The first model is a compartmental one, described by ordinary differential equations, while the other is a distributed parameter model, given by partial differential equations. The comparison is based on the overall number of metastatic cells, changing in time. Various initial tumour sizes, growth rates and time horizons are taken into account.
