This paper comprehensively reviews the dual roles of the cGAS-STING pathway in Luminal, HER2+, and triple-negative breast cancer (TNBC): its activation can enhance antitumor immunity, but chronic activation may lead to immunosuppression. By integrating molecular mechanisms, clinical translation, and subtype-specific strategies, it provides new directions for precision immunotherapy.
