The Advanced Research Progress of Tumor Immunotherapy

The mechanism of tumor formation is extremely complex.Traditional radiotherapy and chemotherapy for tumors have caused irreversible damage to normal tissues and cells when they kill cancer cells in a large area.Therefore, with the research on tumors and tumor microenvironment (TME), immunotherapy and targeted therapy have become the current research hotspots and the future development direction.Immunotherapy for tumors is a treatment strategy that relies on the function of the body's immune system to specifically kill tumor cells or inhibit tumor growth mechanisms.Numerous studies and clinical trials have confirmed the feasibility and effectiveness of this approach, which can alleviate the suffering of cancer patients compared to chemotherapy and radiation therapy.The current clinical treatment of tumors often combines a variety of tumor immunotherapies to form a unified and orderly mechanism to inhibit tumor growth, thereby destroying the hallmark of the tumor to avoid immune destruction.
