ABSTRACT

Modelling Radiation Health Effects

“…Figure 16 shows typical time evolution of the system starting from the initial condition, confluent normal cells mixed with a small number of cells with initiation. We can see the growth of the aggregate of cancer cells by using appropriate parameters (Ouchi, 2007, Ouchi, 2011. 1000 7000 8000 9000 10000 Here, let us define a statistical quantity for criterion of tumourigenesis called "cancer growth rate" (CGR) : time averaged ratio of cancer cells to whole cells (Ouchi, 2011),…”

“…Next, let us begin to model the cell transform process by introducing dynamics of cell type change in the CPM (Ouchi, 2007, Ouchi, 2011. Carcinogenesis process is commonly thought to be a multistage process, in which normal cells are transformed to cancer cells via accumulation of mutations.…”
