Polymeric Nanoparticle-Mediated Targeted Drug Delivery System: A Promising Approach for Breast Cancer

After lung cancer, breast cancer (BC) is the second most frequent malignancy in women globally. Surgery followed by chemotherapy is the conventional treatment plan for BC. However, both are unsuccessful in treating BC because of the harmful effects that these treatments have on healthy tissues and organs. Many polymeric nanoparticles (PNPs) have been discovered and created recently to selectively aim cancer cells without harming normal cells. As an outcome, drug delivery systems (DDS) mediated by NPs have developed as a possible method to treat BC. PNPs have several special qualities that make them ideal for cancer treatment due to their tunable surface functions and choosiness to target tumor cells and minimize side effects
