Abstract
Breast cancer is a significant global health challenge, with rising incidence rates and substantial morbidity and mortality worldwide. Conventional treatments, while effective, often lead to adverse effects and may not fully eradicate cancer cells, resulting in recurrence and progression of tumors. Addressing these challenges requires innovative treatment strategies. Nanotechnology, particularly polysaccharide-based nanoparticles (NPs), offers a promising approach due to their biocompatibility, tunable properties, and targeted drug delivery capabilities. Polysaccharide NPs, including starch, alginate, hyaluronic acid, and chitosan, possess inherent biocompatibility and can be tailored for specific applications. Furthermore, beyond their inherent biocompatibility, polysaccharide-based NPs shown substantial interest due to their natural abundance, ease of processing, and availability from renewable resources, solidifying their role as a sustainable choice for diverse biomedical applications. By functionalizing their surface with ligands, polysaccharide NPs can target breast cancer cells, enhance therapeutic efficacy while minimizing off-target effects. Moreover, these NPs can modulate biological processes relevant to cancer progression, such as angiogenesis and immune response. This review article provides a concise overview of the pathophysiology of breast cancer and the benefits of polysaccharides in drug delivery. Additionally, it emphasizes the significance of several polysaccharide-based NPs in breast cancer therapy, followed by a detailed discussion on the role of various polysaccharide-based NPs in breast cancer treatment.
