title: [Psychosocial stress and the occurrence of cancer - animal experiment results and problems].
abstract: A review of the problems and results of experiments on animals with regard to psycho-social stress and the occurrence of cancer is presented. To a large extent the conflicting results of many studies derive from the problems involved in setting up and establishing reliable experimental conditions for experiments on animals. It is the prerogative of future research to refine experimental design so that an insight can be gained into hitherto unknown relationships. Nevertheless, in spite of varied and conflicting results the available facts provide proof that psycho-social stress factors are capable of influencing the occurrence and progress of carcinogenic illnesses. Our present state of knowledge about these processes is, however, still very slight. The significance of this problem is worthy of more intensive and systematic investigatory experiments on animals within the area of psychosomatic cancer research than has been the case up until now.
