The global Immuno Oncology (IO) market size is expected to reach USD 129.18 billion by 2032, according to a new study by Polaris Market Research. The report “Immuno Oncology (IO) Market Share, Size, Trends, Industry Analysis Report, By Treatment Approaches (Monoclonal Antibodies, Therapeutic Vaccines, Checkpoint Inhibitors, Cytokines); By Novel Targets; By Tumor Types; By Region; Segment Forecast, 2023 - 2032” gives a detailed insight into current market dynamics and provides analysis on future market growth.

Immuno-oncology (IO) is an innovative field that has transformed our understanding of cancer biology and treatment. It focuses on harnessing the power of the body's immune system to combat cancer cells effectively. IO research delves into the intricate relationship between tumors and the immune system, aiming to exploit this interaction for therapeutic purposes. Scientific studies have revealed the immune system's remarkable capability to recognize and eliminate tumors through cancer immunosurveillance, the foundation for IO research.

Clinical trials have proved that certain cancer patients exhibiting tumor-infiltrating T cells tend to have more favorable prognoses. This finding has been observed across various cancer types, including breast cancer, renal cell carcinoma, melanoma, ovarian cancer, and gastrointestinal stromal tumors. It highlights the potential of activating and enhancing the immune response as a promising approach to cancer treatment.
