This paper summarizes professor LIN Yi's clinical experience in treating brain metastases of triple-negative breast cancer （TNBC）. It is believed that the pathogenesis of this disease is fundamentally based on spleen and lung qi deficiency， with the binding of phlegm， stasis， and toxins acting as the critical link for disease progression， and qi stagnation serving as a major factor in its protracted course. The core therapeutic principle of "consolidating the root and cultivating the origin， resolving phlegm and dredging collaterals" is proposed. Clinically， the disease is staged into active， stable， and convalescent phases. During the active phase， characterized by spleen and lung qi deficiency alongside hyperactivity of phlegm-toxin pathogens， the treatment focuses on supplementing qi， fortifying the spleen， resolving phlegm， and dredging collaterals， utilizing the Yiqi Jiangtan Tongluo Formula （益气降痰通络方）. During the stable phase， marked by spleen deficiency， weak qi， and residual phlegm， stasis， and toxins lingering in the collaterals， the treatment aims to fortify spleen， cultivate the origin， expel pathogens， and dredge collaterals， using modified Baihua Qiling Formula （白花芪苓方）. During the convalescent phase， characterized by depletion of healthy qi， dysfunction of zang-fu （脏腑） organs， and deep-seated residual phlegm， stasis， and toxins within the brain collaterals， the treatment focuses on regulating qi movement， protecting body fluids， and applying constitution-based treatments， mostly using mild and nourishing medicinals.

In view of the difficulties and blind spots of western medicine, how to make scientific decisions to standardize the treatment of breast cancer in traditional Chinese medicine and improve the participation of traditional Chinese medicine in the treatment of breast cancer is an important focus of innovative breakthroughs in breast cancer treatment. Based on the clinical experience of Professor LIN Yi, a master of traditional Chinese medicine, and on the basis of "disease identification and syndrome differentiation", this paper summarizes and refines the status of qi and blood imbalance, accumulation of phlegm and blood stasis, viscera deficiency, and cold heat cementation in breast cancer, and further proposes the "six views" of breast cancer balanced treatment: the pathogenesis view focuses on "evil invasion due to vital qi deficiency, and the proliferation of tumors", and the pathogenesis view focuses on "cancer toxin and imbalance of yin and yang", the diagnostic view focuses on "examining the underlying factors and understanding the causes and effects", the differentiation view focuses on "balancing qi, blood, yin, and yang to achieve harmony", the therapeutic view focuses on "supporting vital qi and eliminating evil, and considering the root cause and syndromes", and the rehabilitation view focuses on "adjusting balance to maintain a stable state". We are committed to holistic syndrome differentiation and treatment, balancing yin, yang, qi, and blood, thereby harmonizing the internal environment of the human body, and mobilizing the immune and rehabilitation functions of the body.
