In this paper we present three dimensional cellular automata models for tumour growth, with a focus on the tumour’s natural shrinkage caused by the removal of the dead cells’ mortal remains. The significance of this phenomenon for the resulting volume of the in silico tumour is shown. Two algorithms are presented, one using the chain shifting approach for tumour expansion and shrinkage and another improving the performance of the chain shifting approach. Simulations are validated against the experimental results.
► We present two three dimensional cellular automata models for tumour growth. ► We focus on the tumour’s natural shrinkage. ► We offer several computational adaptations instead of traditional chain shifting. ► Ignoring shrinkage results in wrong tumour volume dynamics and growth pattern.
