Modeling of dose-response relationships. [PDF]
Environmental Health Perspectives, 1981 The main dose-response models for chronic toxicity are considered. For dichotomous response, the log probit, multi-hit, and multistage models are presented. For time-to-occurrence response, the log-normal and three variations of multistage models are presented. Finally, the Cornfield hockey-stick model is considered, and, for low-dose extrapolation, it

Dose-Response Relationships for Carcinogens: A Review [PDF]
Environmental Health Perspectives, 1987 We review the experimental evidence for various shapes of dose-response relationships for carcinogens and summarize those experiments that give the most information on relatively low doses. A brief review of some models is given to illustrate the shapes of dose-response curve expected from them.

Dose-response relationship for breast cancer induction at radiotherapy dose
Radiation Oncology, 2011 Purpose Cancer induction after radiation therapy is known as a severe side effect. It is therefore of interest to predict the probability of second cancer appearance for the patient to be treated including breast cancer.
