Types of Immunotherapy Used in Cancer Treatment
Imagine your immune system as a vigilant security guard, always on patrol, protecting you from harmful intruders like viruses and bacteria. But what if a sneaky invader—like cancer—manages to blend in and go unnoticed? That’s where immunotherapy steps in. It gives your immune system a little nudge (or sometimes a full makeover) so it can recognize and fight cancer effectively.
In this article, we’ll explore the different types of immunotherapy used to treat cancer. Don’t worry—no confusing medical jargon here. We’ll break it down like a friendly chat over a cup of tea. And if you're looking for expert care, Shri Balaji Aarogyam Hospital, Best Oncologist in Kurukshetra, offers advanced and compassionate cancer treatment, including immunotherapy.
What is Immunotherapy?
Immunotherapy is a type of cancer treatment that uses your own immune system to fight cancer. Think of it as training your body’s natural defense force to recognize and destroy cancer cells, which often hide in plain sight.
How Immunotherapy Works
Your immune system is great at spotting invaders. But cancer cells are clever—they can mask themselves as normal cells. Immunotherapy lifts that mask and signals your body to take action. Different types of immunotherapy do this in different ways, which we’ll explain in the next sections.
Monoclonal Antibodies
These are lab-made proteins that mimic the immune system’s ability to fight off harmful invaders.
-
How it works: These antibodies attach to cancer cells and mark them so the immune system can find and destroy them.
-
Analogy: It’s like putting a bright red flag on the enemy so your body’s soldiers can see and attack.
Monoclonal antibodies are already being used successfully for breast cancer, lymphoma, and more.
Immune Checkpoint Inhibitors
Normally, your immune system has brakes to stop it from attacking your own body. Cancer takes advantage of these brakes.
-
Checkpoint inhibitors remove the brakes, allowing your immune system to go full throttle against cancer.
-
Common drugs: Nivolumab, Pembrolizumab, etc.
They’ve been effective in treating lung cancer, melanoma, and others.
Cancer Vaccines
Yes, there are vaccines for cancer, but not quite like the flu shot. These vaccines either prevent certain cancers (like the HPV vaccine for cervical cancer) or treat cancer by boosting the immune response.
-
Therapeutic vaccines help the body fight cancer after it has developed.
-
Preventive vaccines stop cancer from developing in the first place.
CAR T-Cell Therapy
This is one of the most advanced forms of immunotherapy.
-
How it works: Doctors remove T-cells (a type of immune cell), modify them in a lab to better recognize cancer, and then reintroduce them into your body.
-
It’s like turning regular police into a SWAT team trained to find and attack cancer cells.
CAR T-cell therapy is showing great success in blood cancers like leukemia.
Cytokine Therapy
Cytokines are proteins that help immune cells communicate.
-
Types include interleukins and interferons.
-
They enhance the ability of T-cells and other immune cells to fight cancer.
This therapy is used in kidney cancer and melanoma.
Oncolytic Virus Therapy
Sounds sci-fi? It kind of is.
-
Oncolytic viruses are genetically modified viruses designed to infect and kill cancer cells.
-
As they destroy the cancer cells, they release more antigens, alerting the immune system to step in and help.
It’s a double whammy—direct attack and immune activation.
Non-Specific Immunotherapies
These boost the immune system overall, rather than targeting a specific cancer.
-
Often used alongside other treatments.
-
Drugs like interleukin-2 (IL-2) and interferons are common.
It’s like giving your body a healthy dose of motivation to fight harder.
Personalized Immunotherapy
No two patients are the same, and neither is their cancer. That’s where personalized immunotherapy shines.
-
Genetic testing is used to understand the unique makeup of your tumor.
-
Treatment is tailored specifically for you.
Shri Balaji Aarogyam Hospital offers such customized treatment plans, ensuring you get what works best for your body.
How Immunotherapy is Different from Chemotherapy
-
Chemotherapy kills all fast-growing cells—cancerous or not.
-
Immunotherapy trains your immune system to find and kill only cancer cells.
This often means fewer side effects and a more natural approach.
Side Effects of Immunotherapy
Although generally milder than chemo, immunotherapy can still have side effects:
-
Fatigue
-
Skin reactions
-
Fever or chills
-
In rare cases, the immune system may attack healthy organs
Always talk to your doctor about possible risks and how to manage them.
Who is a Candidate for Immunotherapy?
Not all cancers respond well to immunotherapy. Factors include:
-
Type and stage of cancer
-
Genetic makeup of the tumor
-
Overall health
At Shri Balaji Aarogyam Hospital, expert oncologists evaluate whether immunotherapy is right for you.
Future of Immunotherapy in Cancer Treatment
The field is rapidly evolving. Researchers are discovering new ways to enhance the immune system’s ability to fight cancer.
-
AI in drug development
-
Better tumor profiling
-
Combination therapies
The future is hopeful—and hospitals like Shri Balaji Aarogyam are leading the charge in advanced treatment options.
