Why Immunotherapy Might Be Your Cancer-fighting Superhero


In the realm of cancer treatment, immunotherapy has emerged as a revolutionary approach, harnessing the power of the immune system to combat cancer cells. Unlike traditional treatments like chemotherapy and radiation therapy, which directly target cancer cells, immunotherapy works by enhancing the body’s natural defenses to recognize and destroy cancerous cells.

In this blog, we’ll delve into the intricacies of immunotherapy, its effectiveness in cancer treatment, and the types of cancers it can address, shedding light on why it’s considered a potent cancer-fighting superhero.

At What Stage of Cancer is Immunotherapy Used?

Immunotherapy can be utilized at various stages of cancer, depending on the type of cancer, its progression, and individual patient factors. It is most commonly used in the following scenarios:

Advanced or Metastatic Cancer: Immunotherapy is often employed as a treatment option for cancers that have metastasized (spread) to other parts of the body or have become advanced and are no longer responsive to conventional therapies.

Adjuvant Therapy: In some cases, immunotherapy may be administered as adjuvant therapy following surgery or other primary treatments to help prevent cancer recurrence and bolster the body’s immune response against any remaining cancer cells.

Neoadjuvant Therapy: Immunotherapy can also be given before surgery or other primary treatments (neoadjuvant therapy) to shrink tumors, making them more manageable for surgical removal or other interventions.

How Successful is Immunotherapy for Cancer?

The success of immunotherapy varies depending on several factors, including the type of cancer, the stage of the disease, and individual patient characteristics. While immunotherapy has shown remarkable efficacy in certain cancers, its effectiveness may vary from patient to patient. Here are some key points regarding the success of immunotherapy:

Response Rates: In some cases, immunotherapy can lead to significant and durable responses, with tumors shrinking or remaining stable for extended periods. However, not all patients respond to immunotherapy, and response rates may vary depending on the specific cancer type.

Long-Term Survival: Immunotherapy has demonstrated the potential to extend survival in patients with advanced or metastatic cancers, including melanoma, lung cancer, renal cell carcinoma, and certain types of lymphoma.

Combination Therapies: Researchers are exploring combination approaches that combine immunotherapy with other treatments like chemotherapy, targeted therapy, or radiation therapy to enhance efficacy and improve outcomes for patients with cancer.

What Cancers are Treated by Immunotherapy?

Immunotherapy has revolutionized the treatment landscape for various types of cancer, offering new hope for patients with traditionally challenging-to-treat malignancies. Some of the cancers treated by immunotherapy include:

Melanoma: Immunotherapy, particularly immune checkpoint inhibitors like pembrolizumab and nivolumab, has shown significant efficacy in treating advanced melanoma, leading to durable responses and improved survival rates.

Lung Cancer: Immunotherapy has become a standard treatment option for certain types of lung cancer, including non-small cell lung cancer (NSCLC), both as a first-line and subsequent therapy, either alone or in combination with chemotherapy.

Renal Cell Carcinoma (Kidney Cancer): Immune checkpoint inhibitors have demonstrated effectiveness in treating advanced renal cell carcinoma, leading to durable responses and improved survival outcomes for some patients.

Bladder Cancer: Immunotherapy has emerged as a promising treatment option for patients with advanced or metastatic bladder cancer who have progressed on standard chemotherapy regimens, offering the potential for durable responses and improved quality of life.


Immunotherapy represents a groundbreaking approach in cancer treatment, offering new avenues for patients facing various types of malignancies. As research continues to advance and new immunotherapy agents are developed, the potential for harnessing the immune system’s power to fight cancer grows ever brighter. For patients seeking cutting-edge cancer care, consulting with the best cancer hospital in Bangalore can provide access to state-of-the-art treatment options, including immunotherapy, personalized to their individual needs. With the support of skilled healthcare professionals and innovative therapies like immunotherapy, patients can embark on their cancer-fighting journey with confidence and hope for a brighter future.
