Depression Could Shorten Cancer Survival, Study Suggests


(HealthDay News) — Symptoms of depression are linked to shorter survival times among cancer patients, according to a new study.

The link may be attributed to abnormal stress hormone regulation and inflammatory gene expression, researchers from the University of Texas M.D. Anderson Cancer Center reported in the Aug. 1 edition of PLoS ONE.

"Our findings, and those of others, suggest that mental health and social well-being can affect biological processes, which influence cancer-related outcomes," Lorenzo Cohen, a professor in the center’s departments of general oncology and behavioral science, and director of the Integrative Medicine Program, said in a university news release.
