Background: Breast cancer is a significant global health challenge, contributing substantially to cancer- related deaths. Conventional treatment methods, including hormone therapy, chemotherapy, surgical interventions, and radiation, have long been utilized. However, these traditional treatments are often associated with serious side effects and drug resistance, limiting their efficacy. Aim: This review aims to explore the potential of medicinal plants used in breast cancer management in East Africa, focusing on their bioactive compounds and anticancer properties. Methods: A comprehensive literature search was conducted to examine the effectiveness of medicinal plants in treating breast cancer across Kenya, Ethiopia, Uganda, Tanzania, and Rwanda. Relevant studies published between 2003 and 2023 were identified using keywords related to breast cancer and medicinal plants. The search was performed across multiple databases, including Google Scholar, PubMed, Scopus, Web of Science Core Collection, and Science Direct. Results: Numerous natural compounds found in East African medicinal plants including Cymbopogon citratus (Lemongrass,) Tabebuia avellanedae, Prunus africana (African Cherry), Euclea divinorum, Berberis holstii, Withania somnifera (Ashwagandha, Curcuma longa (Turmeric), Garcinia mangostana (Mangosteen, Vitis vinifera (Grapevine), Eugenia jambolana (Java Plum), Moringa oleifera (Drumstick Tree), Camellia sinensis (Tea), Glycine max (Soybean), Catharanthus roseus, Madagascar Periwinkle), Rhus vulgaris (Wild Currant) exhibit significant anticancer properties. These compounds have demonstrated the ability to reduce breast cancer aggressiveness, inhibit cancer cell proliferation, and modulate cancer-related pathways. Current research focuses on these natural and dietary compounds to develop more effective strategies for treating breast cancer. Conclusion: The findings suggested that East African medicinal plants hold promise as complementary treatments for breast cancer, offering potential benefits such as affordability, cultural appropriateness, and sustainability. Further research into these plants and their bioactive compounds could revolutionize breast cancer treatment, improving survival rates and addressing the rising incidence of breast cancer-related fatalities. Other: The review underscores the importance of continued research, conservation, and the integration of ancient healing methods to fully harness the potential of East African flora in breast cancer management.
