A new study that evaluated the effect of stress reduction instructionon survival of patients with breast cancer revealed that this intervention affected survival. 

Relative to the control, the intervention group was found to have a reduced risk of all-cause mortality (HR = 0.21; 95 % CI [0.05, 0.93]; p = .040). Restricting analyses to women with invasive disease revealed significant effects of the intervention on breast cancer-related mortality (p = .006) and disease-free interval (p = .011). Stress reduction intervention delivered post-surgery may provide long-term clinical benefit for non-metastatic breast cancer patients in addition to previously established psychological benefits.
