Background & Objectives Cancer treatment is still one of the main challenges in the field of basic science and clinical science in medicine. Surgery is often the first option in the treatment of cancer, providing the tumor in a way that can be removed. Chemotherapy, radiation therapy, or a combination of both can be used to reduce the tumor in the pre- or post-surgical stage. Hormone therapy, stem cell and bone marrow cell transplantation, and immunotherapy are among other therapeutic approaches. Immunotherapy or the use of the immune system for treatment, after chemotherapy and radiation therapy is one of the most important complementary and effective methods for treating cancer. Immunotherapy such as chemotherapy is systematically done and used to prevent the spread of malignancies, but unlike that only attacks malignant cells and does not effect on normal cells. Cancer, immune therapy with the direct use of immune system components and makes an active immune response such as stimulating the patient's immune system cells and reintroducing these cells to the individual. Indirect stimulation and the use of immune products such as anti-cancer monoclonal antibody to remove tumor antigens is called passive immune therapy. Results The results from clinical trials confirm the design of combined therapies for cancer treatment, which include a combination of various immune therapies along with chemotherapy or the combination of several therapeutic immunotherapy approaches. Conclusion The goal of this review article is to concisely review some of the most important recent developments in cancer immunology and immunotherapy, and explain new insights into the mechanisms that underlie cancer immune evasion by which might lead to pathways for identifying novel treatments.
