Abstract: We develop and calibrate a mathematical model for avascular tumour growth. The model is formulated as a set of partial differential equations describing the spatia-temporal changes in cell concentrations based on reaction-diffusion dynamics and the law of mass conservation. Unlike existing models, the current model takes into account the dependence of the cell proliferation rate on the growth inhibiting factors secreted by necrotic cells; furthermore, the model incorporates an element of random variation to the mitotic rate and nutrient supply. The model is solved using standard finite difference techniques. Results obtained from the simulation compare well with published experimental data. The biological and clinical implications of these results are also discussed.
