Cancer treatment has evolved significantly over the past decade, moving beyond traditional approaches like chemotherapy and radiation. One of the most promising advancements is immunotherapy, a treatment that uses the body’s immune system to identify and destroy cancer cells.
In India, recent breakthroughs in immunotherapy are transforming cancer care by making advanced treatments more accessible, personalized, and effective. This article explores the latest developments, their benefits, and what patients should know.
What Is Cancer Immunotherapy?
Immunotherapy is a type of cancer treatment that helps the immune system recognize and attack cancer cells more effectively. Unlike chemotherapy, which affects both healthy and cancerous cells, immunotherapy is more targeted.
Common types include:
- Checkpoint inhibitors
- CAR-T cell therapy
- Cancer vaccines
- Monoclonal antibodies
These therapies are increasingly being used to treat cancers such as leukemia, lymphoma, lung cancer, and melanoma.
Major Breakthroughs in India
India has made significant progress in cancer immunotherapy, especially in recent years.
Indigenous CAR-T Cell Therapy (NexCAR19)
One of the biggest milestones is the development of India’s first indigenous CAR-T cell therapy, NexCAR19.
- Approved in 2023 for blood cancers like leukemia and lymphoma
- Developed in India, making it more affordable and accessible
- Represents a major step toward self-reliant healthcare
CAR-T therapy works by modifying a patient’s immune cells (T-cells) to attack cancer more effectively.
Expansion of CAR-T Therapy in India
Recent developments have expanded CAR-T therapy availability:
- Approved therapies now available in multiple hospitals across India
- Second CAR-T therapy approved in 2025 for lymphoma treatment
- Response rates in some cases range from 70 to 80% in blood cancers
Additionally, advancements are improving safety and reducing side effects, making treatment more patient-friendly.
Personalized Immunotherapy and Precision Medicine
India is also advancing in personalized cancer treatment, where therapies are tailored to individual patients.
Key innovations include:
- Neoantigen-based vaccines
- Genetic profiling of tumors
- AI-based treatment planning
These approaches allow doctors to design targeted therapies, improving effectiveness and reducing unnecessary side effects.
Immunotherapy for Solid Tumors
Traditionally, immunotherapy has been most effective for blood cancers. However, recent research is expanding its use to solid tumors, such as:
- Lung cancer
- Breast cancer
- Colorectal cancer
Although still under development, early trials show promising results, offering hope for more treatment options in the future.
How Immunotherapy Is Changing Cancer Care
More Targeted Treatment
Immunotherapy focuses on cancer cells specifically, reducing damage to healthy tissues. This leads to fewer side effects compared to traditional treatments.
Improved Survival Rates
In some cancers, immunotherapy has significantly improved survival outcomes and long-term remission rates.
Long-Term Benefits
Unlike chemotherapy, immunotherapy can create a lasting immune response, helping prevent cancer recurrence in some patients.
Availability and Access in India
One of the biggest challenges in advanced cancer care has been cost and accessibility.
Reduced Treatment Costs
- CAR-T therapy in India costs significantly less than in Western countries
- Ongoing development has made advanced treatments more affordable
Expanding Treatment Centers
More hospitals in major cities like Delhi, Mumbai, and Hyderabad are now offering immunotherapy options.
For example, patients in Delhi commonly search for trusted oncology centers offering effective immunotherapy in Delhi that provide access to modern immunotherapy treatments alongside conventional cancer care.
Challenges and Limitations
Despite promising advancements, immunotherapy is not suitable for all patients.
Limited Effectiveness in Some Cases
Not all cancers respond to immunotherapy, especially certain solid tumors.
Side Effects
Possible side effects include:
- Fatigue
- Skin reactions
- Immune-related inflammation
High Initial Costs
Although more affordable in India, advanced therapies can still be expensive for many patients.

Future of Cancer Immunotherapy in India
The future of immunotherapy in India looks promising, with ongoing research focusing on:
- Next-generation CAR-T therapies
- Combination treatments (immunotherapy + chemotherapy)
- AI-driven cancer treatment planning
- Expansion to more cancer types
As technology advances, immunotherapy is expected to become more accessible and effective across a wider range of cancers.
