Immuno-Oncology Drugs Market Forecasted to Reach USD 250 Billion by 2034

Cancer remains one of the most formidable health challenges worldwide, but the past decade has witnessed a paradigm shift in how it is treated. Traditional therapies such as chemotherapy and radiation often bring significant side effects and limited long-term success. In contrast, immuno-oncology (I-O) drugs leverage the body's immune system to recognize and eliminate cancer cells, offering hope for durable responses and improved survival rates.
