Cancer treatment has witnessed significant progress over the past few decades. While surgery, chemotherapy, and radiation have long been the main pillars of care, a new era in oncology is now unfolding—immunotherapy.
This cutting-edge approach uses the body’s own immune system to fight cancer, offering new hope to patients in India and worldwide. With ongoing advancements, immunotherapy is steadily changing the landscape of cancer treatment in India, bringing innovative options for those battling the disease.
Understanding Immunotherapy
Immunotherapy is a type of cancer treatment that stimulates or restores the ability of the immune system to recognize and attack cancer cells. Unlike chemotherapy or radiation, which target cancer cells directly, immunotherapy enhances the body’s natural defenses. The major types of immunotherapy include:
- Immune checkpoint inhibitors – Drugs that block proteins like PD-1/PD-L1 and CTLA-4, which cancer cells use to escape immune attack.
- CAR-T cell therapy – A highly advanced method where a patient’s T-cells are modified in a lab to target cancer cells and then infused back into the body.
- Cancer vaccines – Designed to trigger an immune response against cancer-specific antigens.
- Monoclonal antibodies – Lab-made proteins that mimic immune system functions to attack cancer cells.
These therapies represent a more personalized, targeted approach compared to traditional treatments.
The Impact in India
In recent years, India has begun adopting immunotherapy as part of advanced cancer care. Top oncology centers in cities like Delhi, Mumbai, Bengaluru, and Hyderabad have introduced immune checkpoint inhibitors such as pembrolizumab, nivolumab, and atezolizumab for cancers including lung, head and neck, bladder, and melanoma.
CAR-T cell therapy, considered one of the most promising innovations, has also entered India. In 2021, India saw its first indigenous CAR-T cell therapy trial, developed in collaboration with the Indian Institute of Technology (IIT) Bombay and Tata Memorial Centre.
This breakthrough marks a significant step toward making such therapies more accessible and affordable to Indian patients. For specialized treatment guidance, many patients now consult an experienced Surgical Oncologist in Noida for the latest therapies and care options.
Advantages of Immunotherapy
- Long-lasting remission – Some patients achieve durable responses where cancer stays under control for years, even after treatment stops.
- Targeted action – Unlike chemotherapy, which can harm healthy cells, immunotherapy selectively boosts immune cells to recognize cancer cells.
- Fewer side effects – While not completely side-effect free, immunotherapy often has a more manageable safety profile compared to chemotherapy.
- Potential across multiple cancers – Immunotherapy has shown promise in a wide range of cancers, including melanoma, lymphoma, breast cancer, and lung cancer.
For patients with breast conditions, understanding the early warning signs of breast cancer is equally important for timely diagnosis and improved outcomes.
Challenges in India
Despite its potential, immunotherapy in India faces several challenges:
- High cost – Imported immunotherapy drugs are often prohibitively expensive, limiting accessibility. A single cycle can cost lakhs of rupees, making it out of reach for many.
- Limited awareness – Many patients and families are not fully aware of immunotherapy as an option, relying instead on conventional treatments.
- Infrastructure needs – Advanced therapies like CAR-T require specialized laboratories, trained personnel, and advanced hospital facilities.
- Side-effect management – While generally better tolerated, immunotherapy can sometimes cause immune-related side effects such as colitis, hepatitis, or pneumonitis, requiring expert monitoring.
The Road Ahead
India is steadily progressing toward making immunotherapy more mainstream. Government-backed research programs, collaborations between academic institutions and biotech companies, and the rise of indigenous drug development are key drivers. Local manufacturing of immunotherapy drugs will play a major role in reducing costs and improving accessibility for Indian patients.
Additionally, with increasing clinical trials being conducted in India, patients now have more opportunities to access cutting-edge therapies. Oncologists are also gaining more experience in identifying which patients are most likely to benefit from immunotherapy, leading to more personalized treatment strategies.

Conclusion
Immunotherapy is not just another addition to cancer treatment—it represents a paradigm shift. By harnessing the power of the immune system, it offers renewed hope for patients who may not have responded to traditional treatments.
In India, the journey of immunotherapy has just begun, but its potential is enormous. With continuous research, policy support, and innovation in local manufacturing, immunotherapy can become more affordable and accessible in the coming years.
For patients and healthcare providers alike, this is a new dawn in the fight against cancer—a future where the body’s own defenses become the most powerful weapon against the disease.
