Carciongenesis and Chemoprevention
About the Carcinogenesis and Chemoprevention Program
Frank Ondrey, M.D., Ph.D.
Lisa Peterson, Ph.D.
The scientific goals of the Carcinogenesis and Chemoprevention Program are to elucidate chemical and molecular mechanisms of carcinogenesis and to use this knowledge to develop and evaluate practical methods for cancer prevention. The program has 27 members from 12 departments and institutes within the University of Minnesota.
- Tobacco and cancer
- Chemical and molecular mechanisms of carcinogenesis
- Chemoprevention of cancer
Within these themes, investigators focus on the causes, mechanisms, and prevention of human cancer in a superb collaborative and translational environment.
