EVOLUTION OF METFORMIN IN BREAST CANCER THERAPY IN LAST TWO DECADES: A REVIEW.

Among women, breast cancer is one of the most prevalent cancers. The disease has a complex etiology, with multiple biological pathways contributing to its development. As insulin signaling has mitogenic effects, glucose is a necessary cellular metabolic substrate, and the growth and metastasis of breast cancer are closely related to cellular glucose metabolism. Anti-diabetic medications have drawn increased attention as a potential treatment for breast cancer. Metformin lowers cancer incidence and death rates in patients with type 2 diabetes, according to epidemiologic studies. Preclinical studies conducted in vivo and in vitro offer fascinating new insights into the cellular mechanisms underlying metformin oncostatic action. We present an overview of the mechanisms of anticancer effects of metformin and discuss its potential function as an adjuvant in the treatment of breast cancer.
