Innovative nanodelivery systems for targeted breast cancer therapy: overcoming drug delivery challenges and exploring future perspectives.

Cancer chemotherapy is often limited by insufficient drug targeting, which can cause severe adverse effects on healthy tissues. The advent of nanodelivery systems offers a potential solution to this issue. It intricately enhances drug accumulation in tumor regions, while optimizing drug solubility, ensuring colloidal stability, and promoting cellular uptake, significantly improving the precision and efficacy of treatment, opening a gentler yet more effective new path for cancer therapy. This article begins with the pathogenesis of breast cancer and extends to the current treatment methods and their shortcomings, exploring in-depth the targeting therapeutic effects of five innovative nanodelivery technologies used in the treatment of breast cancer in recent years. Finally, it discusses the potential opportunities and challenges that nanodelivery systems may face in future development.
