[Oncology and psychiatry: Towards mutual connections/relationships]

Oncology has been proposed as a model of scientificity, in order to promote scientific approaches to psychiatry. In this article, another type of relation between oncology and psychiatry is explored, which promotes the idea of a mutually enriching dialogue and underlines the contributions of psychiatry to oncology. The ways in which both fields address epistemological and ethical issues in their respective approaches to disease is also examined. We argue that these two disciplines can learn from one another in the common context of chronic conditions, thanks to the potential of big data collection and their biostatistics treatment for the identification of markers - sources of individualization -, as well as thanks to the renewed attention given to the temporal and processual dimension of these diseases, in particular within the framework of "staging" models.
