A previous study has reported that chronic pain is associated with a higher incidence of overall and site-specific cancer in subsequent years. The aim of this study was to confirm or refute these findings. In 1996, a cohort of 6940 individuals was recruited, and information on chronic pain, general health and socio-demographic details collected. ⋯ After adjustment, these trends remained, although most of the associations were no longer significant. There were no significant differences between those with severe chronic pain compared to those with mild chronic pain. The findings suggest that those with chronic pain are not at a significantly increased risk of developing cancer.
