[Does social support have an impact on the prognosis in cancer?]

Social support is a compound concept. It is being used about different aspects of social integration and about the support provided by people in a social network. Increasing research has been done on the effect of social support on malignant diseases. However, weaknesses in the methodology make it difficult to evaluate the results. For example, the concept of social support may not be adequately defined and the aspects of social support that are studied may be somewhat arbitrary. Both epidemiological research and studies on certain groups of patients support the idea that social support influences our health and our life expectancy. We have reviewed the existing literature on the impact of social support on malignant disease to find out if social support has proven to be of any prognostic value in the case of cancer.
