Immunotherapy for Cancer: Benefits, Types & How It Works
If you or someone you love has just been told that immunotherapy might be part of a cancer treatment plan, it’s normal to feel a mix of hope and confusion at the same time. Cancer treatment already comes with enough new terms to learn, and immunotherapy is often one of the most misunderstood.
It’s important to remember that immunotherapy isn’t the right fit for every patient or every type of cancer. For those it does suit, though, the results can be genuinely life-changing. At Galaxy Care Hospital, Pune, immunotherapy is offered as part of a personalized cancer treatment plan for eligible patients. Let us help you understand immunotherapy and what to expect from it.
What Is Immunotherapy for Cancer Treatment?
According to the NIH, Immunotherapy is a type of cancer treatment that helps your immune system fight cancer. In simple terms, immunotherapy trains your body’s own defence system to find and destroy cancer cells.
Why It Matters: Under normal circumstances, the immune system protects the body by identifying and destroying harmful bacteria, viruses, and abnormal cells. However, cancer cells are clever. They can hide from the immune system or send signals that stop immune cells from attacking them. As a result, cancer continues to grow. This is where immunotherapy treatment plays an important role. It helps remove these barriers, allowing the immune system to recognize cancer cells and respond more effectively.
Unlike chemotherapy, which directly destroys rapidly growing cells, immunotherapy works by strengthening or modifying the body’s natural immune response. For some patients, this can lead to long-lasting control of cancer, even after treatment has ended. Today, cancer specialists may recommend immunotherapy as a standalone treatment or combine it with surgery, chemotherapy, radiation therapy, or targeted therapy, depending on the patient’s condition and treatment goals.
How Does Immunotherapy Help Treat Cancer?
You may be wondering exactly how this process happens inside the body. There isn’t just one method. How immunotherapy works depends on which type is being used, and different types boost the immune response in different ways.
One common type is immune checkpoint inhibitors. Cancer cells often use checkpoint proteins to avoid being attacked by immune cells. These medicines block those proteins, allowing the immune system to recognize and destroy cancer cells.
Another option is monoclonal antibodies. These laboratory-made antibodies attach to specific proteins found on cancer cells, making them easier for the immune system to locate. Some monoclonal antibodies also deliver treatment directly to cancer cells.
CAR T-cell therapy is a more specialized form of immunotherapy used mainly for certain blood cancers. In this treatment, a patient’s own immune cells are collected, modified in a laboratory to better recognize cancer, and then returned to the body.
Cancer vaccines are another approach, designed either to prevent certain cancers or to trigger a stronger immune response once cancer is already present.
Not every patient receives every type of immunotherapy. The right approach depends on the cancer type, its stage, and the patient’s overall health, which is why treatment planning is always personalised rather than one-size-fits-all.
Which Types of Cancer Can Be Treated with Immunotherapy?
Cancer immunotherapy has shown strong success rate and 5 years survival rate in several cancers, including:
- Lung cancer
- Melanoma (a type of skin cancer)
- Kidney cancer
- Bladder cancer
- Head and neck cancers
- Certain breast cancers
- Blood cancers such as leukaemia and lymphoma
The good news is that research in this field continues to expand, and more cancers are being studied for immunotherapy eligibility every year. That said, immunotherapy is not suitable for every cancer or every patient. Oncologists rely on detailed testing, including biomarker analysis, along with the cancer’s stage and the patient’s general condition, before recommending it as part of a cancer treatment plan.
What Are the Benefits and Possible Side Effects of Immunotherapy?
Let’s understand this simply by looking at both sides.
Benefits
The immunotherapy benefits that draw both doctors and patients toward this treatment include:
- A more targeted approach compared to some traditional treatments
- The possibility of a longer-lasting response in certain cancers
- The option to combine it with surgery, chemotherapy, radiation, or targeted cancer therapy for a more complete treatment strategy
- Improved quality of life for some patients during and after treatment
- A reduced chance of recurrence in specific cancer types
Side Effects
Because immunotherapy works by activating the immune system, it can sometimes cause the immune system to become overactive. Common immunotherapy side effects include:
- Fatigue
- Skin rash
- Fever
- Diarrhoea
- Changes in thyroid function
- Inflammation that can affect organs such as the lungs, liver, or intestines
Here’s what you should know: side effects vary quite a bit from person to person, and even the same drug can affect two patients differently. Any new or worsening symptom should always be reported to your oncology team right away, so it can be managed early and effectively.
Who Is a Good Candidate for Immunotherapy?
There’s no single test that tells a patient whether immunotherapy will work for them. Instead, our cancer specialists at Galaxy Care Hospital look at the full picture. This includes the specific cancer type, results from biomarker testing, the patient’s overall health, and any treatments they’ve already tried.
This kind of personalized cancer treatment planning works best when it comes from a multidisciplinary team, to build a plan around the patient rather than the diagnosis alone. If you’re exploring treatment options, it’s worth having an honest conversation with an experienced oncology team about whether immunotherapy could be part of your journey.
Is Immunotherapy the Right Treatment for You?
Immunotherapy has genuinely reshaped what’s possible in cancer care for many patients, offering options that simply didn’t exist a generation ago. At the same time, it’s not a universal solution, and the right treatment always depends on individual factors.
At Galaxy Care Hospital, Pune, cancer treatment is built around understanding each patient’s unique needs. Dr. Shailesh Puntambekar and the experienced multidisciplinary oncology team work closely with patients to create a personalised cancer treatment plan supported by advanced diagnostic facilities and modern treatment approaches, ensuring comprehensive cancer care under one roof.
If you or your loved one is exploring immunotherapy in Pune, we are here to help you understand the available options, answer your concerns, and create a treatment approach focused on your health, comfort, and well-being.
Frequently Asked Questions
1. Is immunotherapy better than chemotherapy?
Neither treatment is universally “better.” They work differently and are often used together rather than as competitors. Immunotherapy helps the immune system target cancer cells, while chemotherapy directly attacks fast-growing cells throughout the body. The right choice, or combination, depends on the cancer type, stage, and the patient’s overall health.
2. How long does immunotherapy treatment take?
Treatment duration varies widely based on the cancer type and how the patient responds. Some patients receive immunotherapy for several months, while others continue for a year or longer. Your oncologist will monitor your response through regular scans and tests to decide how long treatment should continue.
3. What are the success rates of immunotherapy for cancer?
Success rates depend heavily on the cancer type, stage, and individual patient factors, so there’s no single number that applies to everyone. Some cancers, like melanoma and certain lung cancers, have shown particularly strong responses and high success rates. Your oncology team can give you a realistic picture based on your specific diagnosis.
4. Does immunotherapy have fewer side effects than chemotherapy?
Not necessarily fewer, but often different. Immunotherapy side effects usually relate to an overactive immune response, such as fatigue, rash, or organ inflammation, while chemotherapy side effects often involve the digestive system, blood counts, and hair loss. Both require close monitoring by your care team.
5. Where can I get immunotherapy in Pune?
Galaxy Care Hospital, the leading cancer hospital, offers immunotherapy in Pune as part of a comprehensive, multidisciplinary approach to cancer care. Patients have access to advanced diagnostics along with surgery, chemotherapy, radiation, targeted therapy, and immunotherapy, all coordinated by an experienced oncology team under one roof.
