Television actress Dipika Kakar has recently started immunotherapy as part of her cancer treatment, according to updates shared by her husband Shoaib Ibrahim. The news has sparked curiosity among many people who want to understand what immunotherapy is and how it differs from other cancer treatments.
Cancer treatment has changed significantly over the years. Today, doctors have several options to treat different types of cancer. These include surgery, chemotherapy, radiation therapy, targeted therapy and immunotherapy. Among these, immunotherapy is considered one of the most important medical advances in recent years because it works in a completely different way.
Unlike chemotherapy, which directly attacks cancer cells, immunotherapy helps the body's own immune system recognize and fight cancer more effectively. This unique approach has helped many patients and has opened new possibilities in cancer care.
The human immune system is designed to protect the body from infections, viruses, bacteria and abnormal cells. Normally, it can identify harmful cells and destroy them. However, cancer cells are often able to hide from the immune system. They can develop mechanisms that prevent the body's natural defenses from recognizing them as a threat.
When this happens, cancer cells continue to grow and spread. Immunotherapy is designed to overcome this problem. It helps the immune system detect cancer cells and attack them more effectively.
According to cancer specialists, immunotherapy does not directly kill cancer cells in the same way chemotherapy does. Instead, it strengthens or reactivates the immune system so that it can perform its job better. This is why many doctors describe immunotherapy as a treatment that empowers the body's natural defense system.
Different types of immunotherapy are available today. Some medicines remove the "brakes" that prevent immune cells from attacking cancer. Others boost immune activity or help the immune system target specific cancer cells. The type of immunotherapy used depends on the patient's condition and the nature of the cancer.
One reason immunotherapy has gained attention is because it has produced encouraging results in several difficult-to-treat cancers. In some patients, it has helped control disease progression and improve survival rates.
However, doctors emphasize that immunotherapy is not suitable for every patient. Treatment decisions are always made after careful evaluation of multiple factors.

Many people compare immunotherapy with chemotherapy because both are used to treat cancer. However, the two treatments work very differently.
Chemotherapy attacks rapidly dividing cells in the body. Since cancer cells grow quickly, chemotherapy can destroy them. However, chemotherapy can also affect healthy cells that divide rapidly, such as those in hair follicles, the digestive system and bone marrow. This is why chemotherapy often causes side effects such as hair loss, nausea and fatigue.
Immunotherapy follows a different approach. Rather than targeting cancer cells directly, it helps the immune system recognize and attack them. Because of this, the side effects and treatment experience may differ from those associated with chemotherapy.
Doctors decide which treatment is most appropriate based on several factors, including the type of cancer, its stage, the patient's overall health and specific biological features of the tumor.
Over the past decade, immunotherapy has shown significant success in treating several cancers. These include lung cancer, melanoma, kidney cancer, bladder cancer and some cancers of the head and neck region. Researchers continue to study its effectiveness in many other types of cancer as well.
Despite its success, immunotherapy is not a universal cure. Some patients respond extremely well, while others may experience limited benefits. Scientists are still working to understand why certain patients respond better than others.
Before recommending immunotherapy, doctors often conduct specialized tests to look for molecular markers or other characteristics that can help predict whether the treatment is likely to work. This personalized approach is one reason modern cancer care has become increasingly tailored to individual patients.
Experts describe immunotherapy as a major breakthrough because it has created new treatment opportunities for people who previously had limited options. In some advanced cancers, it has helped patients live longer and maintain a better quality of life.
The growing awareness around Dipika Kakar's treatment journey is also helping people learn more about modern cancer therapies. It highlights how cancer treatment today is no longer limited to traditional methods alone. Medical science now offers multiple approaches that can be customized according to each patient's needs.
While immunotherapy is not suitable for every case, it represents an important advancement in cancer care. By helping the immune system fight cancer more effectively, it has changed the way doctors treat many forms of the disease and has given hope to countless patients around the world.
As research continues, experts believe immunotherapy will play an even greater role in future cancer treatment strategies, offering new possibilities for better outcomes and improved patient care.
