The Sociobehavioural Cancer Research Network (SCRN) was established in 1994 by the National Cancer Institute of Canada (NCIC) with funding from the Canadian Cancer Society (CCS). The network was created to facilitate the development of behavioural science studies that would contribute to a fuller understanding of the cancer experience, from prevention through detection, treatment and post treatment (including palliative care). This article describes the nature of network research, the development and organization of the Sociobehavioural Cancer Research Network and the challenges it faces.
