For centuries, cancer has remained the leading cause of death worldwide
despite the advancements in chemotherapy and immunotherapy. The challenges of
tumor heterogeneity, drug resistance, and systemic toxicity have impeded effective
cancer treatment. The rising number of cancer-related deaths has placed significant
pressure on healthcare systems and biopharmaceutical companies to develop new
therapeutic approaches. Fortunately, recent advancements in nanotherapies have shown
promising results in tackling these obstacles and reducing the risk of multidrug
resistance. Nanotherapies have emerged as a key player in cancer treatment by enabling
targeted delivery of drugs and minimizing the side effects associated with systemic
toxicity. By addressing the limitations of current treatment methods, these innovative
strategies offer a new frontier in both cancer screening and treatment. In this chapter,
we will explore the role of nanotherapies in cancer and their potential to overcome the
challenges faced in conventional cancer treatments.
Keywords: Chemotherapy, Cancer, Drug delivery, Nanotherapies, Systemic toxicity.
