Prolonged Work-Related Stress May Cause Cancer in Men

For men, prolonged exposure to work-related stress has been linked to an increased likelihood of lung, colon, rectal and stomach cancer and non-Hodgkin lymphoma, a new study has warned. 

Researchers, including those from University of Montreal in Canada, assessed the link between cancer and work-related stress perceived by men throughout their working life. 

On average, the study participants had held four jobs, with some up to a dozen or more during their working lifetime. 

Significant links to five of the 11 cancers considered in the study were revealed. These links were observed in men who had been exposed to 15 to 30 years of work-related stress, and in some cases, more than 30 years, PTI reported from Toronto.

A link between work-related stress and cancer was not found in participants who had held stressful jobs for less than 15 years, researchers said. 

The most stressful jobs included firefighting, industrial engineering, aerospace engineering, mechanic foremanship and vehicle and railway-equipment repair.

Stress varied depending on the job held. Researchers were able to document changes in perceived work-related stress. 

The study also shows that perceived stress is not limited to high work load and time constraints. Customer service, sales commissions, responsibilities, the participant’s anxious temperament, job insecurity, financial problems, challenging or dangerous work conditions, employee supervision, interpersonal conflict and a difficult commute were all sources of stress listed by the participants. 

The results obtained raise the question of whether chronic psychological stress should be viewed as a public health issue, they said. The research was published in the journal Preventive Medicine.
