    Weibull-like Model of Cancer Development in Aging by Tengiz Mdzinarishvili, Simon Sherman

    Published 2010-01-01
    “…In this work, for mathematical modeling of cancer hazards, we proposed to use the Weibull-like function, derived from the Armitage-Doll multistage concept of carcinogenesis and an assumption that number of clones at age t developed from mutated cells follows the Poisson distribution. This function is characterized by three parameters, two of which ( r and λ) are the conventional parameters of the Weibull probability distribution function, and an additional parameter ( C 0 ) that adjusts the model to the observational data. …”
