                                        Abstract

                                        As a pathologically heterogeneous disease, cancer is one of the leading causes of
                                        global morbidity. According to the World Health Organization, approximately one in
                                        six deaths are caused by cancer. Fortunately, many cancers can be cured if diagnosed
                                        at early stages and treated efficiently. Despite the benefits of conventional cancer
                                        treatments such as surgery, chemotherapy, hormone therapy, and radiation therapy,
                                        they have several drawbacks, including cytotoxicity, inaccurate targeting of tumor
                                        cells, and multi-drug resistance, which underscore the importance of developing
                                        novel and effective strategies to improve diagnosis, prognosis, therapy, and patient
                                        survival. Recently, the advancement of nanotechnology has opened new horizons for
                                        cancer treatment thanks to the discovery of nanoparticles (NPs) and the small-sized
                                        molecules that revolutionized the drug delivery methods in cancerous tissues. The
                                        specific characteristics of NPs, such as reduced toxicity, improved permeability, and
                                        accurate targeting of tumor cells, provide a great advantage in cancer treatment and
                                        help to overcome the limitations and challenges of conventional cancer treatment
                                        methods. Besides, the role of NPs in immunotherapy has created a novel concept for
                                        cancer treatment. This review gives a brief overview regarding the importance of NPs
                                        and their targeting mechanism, as well as the challenges and limitations associated
                                        with their use in cancer treatment.
