Immunotherapy: The New Frontier in Cancer Treatment

Cancer treatment has evolved tremendously over the past few decades. Among the most promising advances today is immunotherapy—an innovative approach that empowers the body’s own immune system to fight cancer cells.
Once seen as a dream for the future, immunotherapy is now a reality that is changing the lives of thousands of cancer patients worldwide.

In this blog, we’ll explain what immunotherapy is, how it works, its types, and why Dr. Sumant Gupta, the best cancer specialist in Faridabad, is the trusted name for cutting-edge cancer care.

What is Immunotherapy?

Immunotherapy is a type of cancer treatment that stimulates or restores the ability of the immune system to recognize and destroy cancer cells.
Unlike chemotherapy or radiation that attack cancer cells directly, immunotherapy strengthens your body’s natural defenses to identify and eliminate cancer more effectively.

It’s often referred to as the “fifth pillar of cancer treatment” after surgery, chemotherapy, radiation therapy, and targeted therapy.

How Immunotherapy Works

Cancer cells are tricky. They often find ways to evade the immune system by disguising themselves as normal cells.
Immunotherapy works by:

  • Boosting the immune system’s response to cancer

  • Marking cancer cells so the immune system can find and destroy them

  • Blocking cancer cells’ ability to evade detection

This targeted approach offers long-lasting protection, sometimes even after the treatment has ended.

Types of Immunotherapy for Cancer

1. Checkpoint Inhibitors

These drugs unblock immune checkpoints, allowing T-cells to recognize and attack cancer.
Examples include:

  • PD-1 inhibitors (e.g., nivolumab, pembrolizumab)

  • PD-L1 inhibitors

  • CTLA-4 inhibitors

2. CAR T-Cell Therapy

In this advanced treatment, a patient’s T-cells are modified in the lab to better attack cancer cells and then reintroduced into the body.

3. Cancer Vaccines

Unlike traditional vaccines that prevent diseases, cancer vaccines help the immune system attack cancer cells after the disease has developed.

4. Monoclonal Antibodies

Lab-made proteins that bind to specific targets on cancer cells and mark them for destruction by the immune system.

5. Cytokine Therapy

Cytokines like interferons and interleukins boost the immune system’s response against cancer.

Benefits of Immunotherapy

  • Targets cancer cells specifically with fewer side effects compared to chemotherapy

  • Potential for long-term remission

  • Effective for cancers that don’t respond to other treatments

  • Strengthens overall immune function

  • Can work synergistically with other cancer treatments

Which Cancers Can Immunotherapy Treat?

Immunotherapy is currently approved or being tested for:

  • Lung cancer

  • Melanoma (skin cancer)

  • Kidney cancer

  • Bladder cancer

  • Head and neck cancers

  • Blood cancers like lymphoma and leukemia

  • Cervical cancer

  • Esophageal cancer

With ongoing research, more cancers are being added to the list every year.

Challenges and Considerations

While immunotherapy offers hope, it’s not a universal solution:

  • Not all patients respond equally

  • Some may experience autoimmune-like side effects

  • Requires expert evaluation and monitoring for best outcomes

This is why consulting an experienced oncologist is crucial when considering immunotherapy as a treatment option.
