Subtypes of BC, including HER2-positive or triple-negative BC, exhibit differing treatment responses; consequently, demand for personalized therapy is increasing, and relevant precision medicine strategies are under development. Aerobic glycolysis in cancer cells can lead to excessive lactate production, which in turn promotes lactylation and influences tumor cell behavior. Epigenetic alterations and metabolic reprogramming are prominent characteristics of tumors. Because lactate and lactylation are |\n| --- | --- |\n| KEYWORDS | important in cancer, further investigation of the mechanisms underlying lactate metabolism and lactylation, and the development of therapeutic strategies targeting these processes, are topics of increasing interest. This review describes current research on lactate metabolism and lactylation in BC, thus offering new perspectives for advancing treatment and management toward more precise and personalized approaches that will ultimately increase BC survival rates and patient quality of life.\u003Cbr>Lactate; lactylation; breast cancer; tumor metabolism; immunotherapy prognosis |\n\nIntroduction  \nBreast cancer (BC), a major public health challenge globally, is a life-threatening disease and a major cause of mortality in women1-4. BC also shows high heterogeneity, and aggressive and complex biological characteristics5,6 . Various treatments, such as immunotherapy, emerging targeted inhibitors, antibody-drug conjugates, nanoparticles (such as albumin-based, metal-based, lipid-based, polymer-based, and micelle-based nanoparticles), and therapeutics targeting BC stem cells, are available for treating BC7-10. However, effective treatment of BC faces numerous challenges, including the poor  \n*These authors contributed equally to this work.
