Immunotherapy by best Cancer Specialist in Delhi


Immunotherapy is a revolutionary approach to treating cancer, by leveraging the body’s immune system to fight and eliminate abnormal cells. Unlike traditional treatments like chemotherapy and radiation, which directly target cancer cells, immunotherapy enhances the body’s natural defense mechanisms to identify and destroy cancer cells more effectively.

Immunotherapy works by manipulating the immune system, which is responsible for recognizing and neutralizing foreign invaders in the body. It involves using substances that stimulate the immune response or enhance its ability to identify and attack specific targets.

One key aspect of immunotherapy is checkpoint inhibitors. These inhibitors block certain proteins that restrain the immune system, allowing immune cells to recognize and attack cancer cells more effectively. Another approach involves CAR-T cell therapy, where T cells are genetically engineered to recognize and destroy cancer cells specifically

Types of Immunotherapy

Checkpoint Inhibitors

Checkpoint inhibitors are a type of immunotherapy that blocks checkpoint proteins like PD-1 or CTLA-4, which cancer cells exploit to evade the immune system. By inhibiting these checkpoints, the treatment enhances the immune response against cancer cells.

CAR-T Cell Therapy

CAR-T cell therapy is a personalized immunotherapy approach where a patient’s T cells are collected, genetically modified to express chimeric antigen receptors (CARs), and infused back into the patient. These CAR-T cells can then target and attack cancer cells with specific antigens.

Monoclonal Antibodies

Monoclonal antibodies are lab-created antibodies designed to target specific antigens on cancer cells. They can mark cancer cells for destruction by the immune system or deliver drugs directly to cancer cells.

Cancer Vaccines

Cancer vaccines are designed to stimulate the immune system to recognize and attack cancer cells. They may contain tumor-specific antigens or immune-boosting substances to trigger an immune response against cancer cells.

Lung Cancer Immunotherapy by best Cancer Specialist in Delhi

Immunotherapy for Different Cancers

Lung Cancer

In lung cancer, immunotherapy has been successful in improving survival rates for certain patients, especially when combined with other treatments.

Breast Cancer

Although immunotherapy has not been as effective in all breast cancer cases, ongoing research aims to identify subgroups that may benefit from this approach.


Immunotherapy has shown remarkable success in treating advanced melanoma, leading to durable responses in some patients.

Leukemia and Lymphoma

Certain forms of leukemia and lymphoma have responded well to immunotherapy, providing new hope for patients with these blood cancers.

Benefits of Immunotherapy

  • Targeted Treatment: Immunotherapy can specifically target cancer cells, reducing damage to healthy cells.
  • Long-Term Effects: Some patients experience long-lasting remission after immunotherapy treatment.
  • Combination Potential: Immunotherapy can be combined with other treatments for enhanced effectiveness.

Immunotherapy plays a crucial role in cancer treatment by harnessing the body’s immune system to target and eliminate cancer cells. It offers a promising alternative to traditional treatments like chemotherapy and radiation.

Yes, certain cancers have shown better responses to immunotherapy. Melanoma, lung cancer, kidney cancer, and some types of lymphoma are among the cancers that have demonstrated positive outcomes with immunotherapy.

Checkpoint inhibitors work by blocking certain proteins that restrain the immune system, allowing it to recognize and attack cancer cells more effectively. They are used in various cancers, including melanoma, lung cancer, bladder cancer, and some types of head and neck cancers.

While immunotherapy generally causes fewer severe side effects than traditional treatments, it can still lead to immune-related adverse events. These may include fatigue, skin rash, diarrhea, and in rare cases, more serious immune reactions.

Yes, immunotherapy is often used in combination with other treatments like chemotherapy, targeted therapy, and radiation. This combination approach can improve treatment efficacy in some cases.

Immunotherapy may not be suitable for all cancer patients, as its effectiveness varies depending on the type of cancer and individual patient factors. It is essential to assess each patient’s specific situation to determine the best treatment plan.

As an oncologist, I will evaluate your medical history, cancer type, stage, and overall health to determine if immunotherapy is a viable treatment option for you.

The field of immunotherapy is continuously evolving, and we anticipate exciting advancements. Personalized immunotherapy, combination therapies, and the development of new immunotherapeutic agents hold promise for improving cancer treatment outcomes in the future.
