Increased cancer-specific mortality in individuals developing mental disorders after cancer diagnosis: biomedical factors versus psychosocial support

The role of mental health is gaining greater prominence in outcomes research; and increasingly, recent studies are investigating cancer-related outcomes (1,2), including cancer screening, stage at diagnosis, receipt of treatment, and survival, in the presence of comorbid mental conditions.
