A meeting report is given (Annual Symposium on Fundamental Cancer Research, Houston, and International Congress of Nutrition, San Diego) which mainly deals with cancerogenesis: The role of retinoids as inhibitors, and the role of pyrolysis products as promoter of cancerogenesis, both essentially active in the tumor promotion range of cancerogenesis, after previous initiation. In the future, enhanced chances may be foreseen for active prevention and for causal elucidation of cancer formation, which until now seems to be a spontaneous disease.
