Objectives: To investigate the impact of depression and anxiety on developing breast cancer through immune disturbance pathway Methodology: The present study is a descriptive review of systematic review studies conducted in accordance with the guidelines for preferred cases for reporting systematic and metaanalysis review articles (prisma). Electronic databases including ISI Web of Knowledge, PubMed, and Scopus, were searched from 2012 to 2020.

Conclusions: A better understanding of the bidirectional communication between the neuroendocrine and immune systems could contribute to new clinical and treatment strategies.
