From: Similarities between pandemics and cancer in growth and risk models
Exponential growth of cancer cells. (a) Variability in cancer due to an increase in risk with age of four individuals belonging to groups indicated by: H, high; L, low; P, predisposition; D, dose. The values for predisposition are: τ0 = 5 y (HP), τ0 = 20 y (LP). The effect of age and absorbed dose is reflected by the values: b= − 0.01 y−1 (HD), and b = − 0.005 y−1 (LD). (b) Exponential growth in cancer cells after crossing the risk-threshold illustrated in (a).
