Overview
New York, NY – Dec 12, 2025 – Global Cancer Immunotherapy Market size is expected to be worth around US$ 691.0 Billion by 2034 from US$ 226.5 Billion in 2024, growing at a CAGR of 11.8% during the forecast period 2025 to 2034. In 2024, North America led the market, achieving over 41.1% share with a revenue of US$ 93.1 Billion.
Cancer immunotherapy is an advanced treatment approach that is designed to strengthen the body’s own immune system to identify, target, and eliminate cancer cells. Unlike traditional cancer treatments such as chemotherapy and radiation therapy, which directly destroy cancer cells, immunotherapy works by enhancing natural immune responses or restoring immune functions that cancer cells suppress.
The immune system is naturally equipped to detect abnormal cells. However, cancer cells often develop mechanisms to evade immune recognition. Cancer immunotherapy addresses this challenge by modifying immune pathways, activating immune cells, or removing barriers that prevent the immune system from functioning effectively. As a result, immune cells such as T cells can better recognize cancer-specific markers and initiate a targeted attack.
Several major types of cancer immunotherapy are currently used in clinical practice. These include immune checkpoint inhibitors, which block proteins that limit immune responses; monoclonal antibodies, which bind to specific cancer antigens; cancer vaccines, which stimulate immune recognition of tumor cells; and adoptive cell therapies, where immune cells are engineered or expanded outside the body and reinfused into the patient.
Immunotherapy has demonstrated significant clinical benefits across multiple cancer types, including melanoma, lung cancer, breast cancer, and certain blood cancers. In many cases, durable and long-term responses have been observed, indicating sustained immune protection against disease recurrence.
Ongoing research and clinical trials continue to expand the applications of cancer immunotherapy. Advances in biomarker identification, combination therapies, and personalized treatment strategies are expected to further improve patient outcomes. Cancer immunotherapy is increasingly viewed as a critical component of modern oncology and a key driver of innovation in cancer treatment.

- Rising Importance of Immunotherapy in Cancer Treatment: Cancer immunotherapy has become a prominent therapeutic approach by leveraging the body’s immune system to identify and eliminate cancer cells. This treatment modality has demonstrated strong clinical outcomes, particularly in melanoma, lung cancer, and certain lymphomas, where improvements in survival rates have been consistently reported.
- Key Applications of Cancer Immunotherapy: Several immunotherapy modalities have been extensively researched and adopted in clinical practice. These include immune checkpoint inhibitors, CAR-T cell therapy, and therapeutic cancer vaccines. Among these, immune checkpoint inhibitors especially PD-1 and PD-L1 inhibitors have significantly transformed treatment protocols for non-small cell lung cancer and melanoma, improving response rates and long-term outcomes.
- Global Cancer Burden: Prevalence and Mortality: In 2022, global cancer incidence reached approximately 20 million new cases, while cancer-related mortality stood at 9.7 million deaths. Lung cancer remained the most prevalent malignancy, with 2.5 million new cases, and was also the leading cause of cancer deaths, accounting for 1.8 million fatalities, or 18.7% of all cancer-related deaths worldwide.
- Five-Year Cancer Survival Trends: The global number of cancer survivors within five years of diagnosis was estimated at 53.5 million. However, survival outcomes vary significantly across populations. For example, in cervical cancer, five-year survival rates in the United States were estimated at 71% among white women, compared with 58% among black women, highlighting persistent disparities in healthcare access and outcomes.
- Geographic Inequalities in Cancer Outcomes: Approximately 70% of global cancer deaths occur in low- and middle-income countries, where access to advanced cancer care, including immunotherapy, remains limited. Less than 30% of low-income countries provide comprehensive cancer treatment services, compared with nearly 90% coverage in high-income countries, underscoring a significant global treatment gap.
- Cancer Coverage within Universal Health Systems: According to a World Health Organization survey, only 39% of countries include basic cancer management within their core health service packages. In addition, just 28% of countries offer palliative care services, including pain management, as part of universal health coverage, indicating insufficient integration of cancer care in many national health systems.
- Potential Impact of Improved Cancer Strategies: It has been estimated that up to 3.7 million lives could be saved each year through resource-appropriate interventions, including prevention, early diagnosis, and timely access to effective treatments such as immunotherapy. These strategies are particularly critical in resource-constrained settings.
- Immunotherapy and the Future of Oncology: Immunotherapy is expected to play an increasingly central role in the future of cancer treatment. Advances in personalized medicine, including therapies targeting specific genetic and molecular characteristics of tumors, are anticipated to improve treatment precision and outcomes. Ongoing global research and innovation in immunotherapy remain essential to enhancing survival rates and expanding alternatives to conventional treatments such as chemotherapy.
