Cancer is an extremely proliferative illness with several causes, including aberrations in cell cycle control and apoptosis, DNA damage, an impaired repair mechanism, and so forth. Multiple kinds of immune cells, both innate and adaptive, are found in the cancer microenvironment and play a significant role in the development of the illness. The chemicals generated by inflammatory cells in the cancer microenvironment are the most crucial in establishing a link between inflammation, innate immunity, adaptive immunity, and cancer. Anti-tumorigenic and pro-tumorigenic responses in cancer may be triggered by chemicals released by immune cells. The balance between immunosuppressive and immunostimulatory signals within the inflammatory milieu plays a crucial role in tumour suppression. Immunotherapeutic strategies may be more useful in the fight against cancer. The chances for immunotherapy, both on its own and in conjunction with conventional medicines, are, nevertheless, increasing as immunobiology and cancer research continue to develop. As a result, this review makes an effort to highlight a potential and future-looking immunotherapeutic technique that may be used in conjunction with standard treatment methods.
