Drug resistance remains a major challenge in cancer treatment, significantly limiting the
effectiveness of chemotherapy. This research paper investigates the mechanisms of drug
resistance in cancer, exploring genetic, cellular, and microenvironmental factors that
contribute to this phenomenon. The paper examines common molecular mechanisms, such as
drug efflux, mutations in drug targets, and alterations in apoptosis signaling. Additionally, the
paper discusses the role of tumor heterogeneity and the microenvironment in drug resistance,
highlighting the challenges and opportunities for overcoming these barriers. Finally, the
paper explores novel strategies and therapeutic approaches aimed at addressing chemotherapy
resistance, including combination therapies, targeted treatments, and immunotherapy. These
strategies hold promise for improving cancer treatment outcomes and reducing the prevalence
of drug resistance in clinical settings.
