Stress Disorder Not Linked To Cancer Risk

Stress disorder not linked to Cancer risk

In the largest study of its kind, researchers have found that stressful life events are not linked to increased cancer risk. "This study provided no evidence that a severe chronic stress disorder such as post traumatic stress disorder (PTSD) is associated with cancer incidence," said corresponding author Jaimie Gradus, assistant professor of Psychiatry and Epidemiology at Boston University School of Medicine (BUSM) in the US.

ISLAMABAD, (UrduPoint / Pakistan Point News - 12th Sep, 2018 ) :In the largest study of its kind, researchers have found that stressful life events are not linked to increased cancer risk. "This study provided no evidence that a severe chronic stress disorder such as post traumatic stress disorder (PTSD) is associated with cancer incidence," said corresponding author Jaimie Gradus, assistant professor of Psychiatry and Epidemiology at Boston University school of Medicine (BUSM) in the US.

"The general public may have a perception that stress contributes to cancer occurrence and given the ubiquity of PTSD and cancer and their costs to individuals and society, any observed associations could have meaningful public health implications," Gradus explained.

The association between stress and cancer has been discussed in scientific literature for more than 70 years. Despite plausible theories that would support this association, findings from clinical research have been mixed, said the study published in the European Journal of Epidemiology.

According to the researchers, the large sample and long study period allowed them to examine associations that have not been studied previously as they were able to look at rare cancer outcomes and associations among important subgroups.
