Psychosocial factors may play a role in cancer aetiology. Potential mechanisms proposed include an alteration of the immune function and/or of hormone levels. Several studies have suggested a link between stress and breast cancer risk. Hardly any evidence exists for other cancer types. Prostate cancer is thought to be influenced, at least in part, by environmental circumstances modulating hormone levels. We report here on the association between lifelong stress at work and prostate cancer risk in the context of a case-control study involving 973 incident, pathology confirmed prostate cancer cases and 1,087 population controls in Montreal, Canada. As part of in-person interviews, subjects were asked to provide a detailed description of each job held over their lifetime, including specific tasks, and were asked to indicate whether these jobs made them feel tense, anxious or stressed. Regression analysis was used to estimate odds ratio (OR) and 95% confidence intervals (CI) associated with stress at work, while adjusting for age, ethnicity, first-degree family history of prostate cancer and education. Compared to men reporting no work-related stress, the OR among those who did increased with longer cumulative durations of work-related stress (p for trend = 0.023). The ORs for prostate cancer according to the duration of work-related stress were: OR(1-10 years) = 1.12, 95%CI 0.81-1.54; OR(11-20 years) = 1.17, 95%CI 0.87-1.58; OR(21-30 years) = 1.32, 95%CI 1.00-1.74; OR(more than 30 years) = 1.29, 95%CI 1.02-1.64. Results remained unaltered when income, smoking, alcohol intake and body mass index were accounted for. Our findings of an association between work-related stress and prostate cancer are largely novel and require replication in other studies.
