What is Immunotherapy?
Immunotherapy is a type of cancer treatment that helps your immune system fight cancer. It works by stimulating your immune system to recognize and attack cancer cells. This is important because sometimes cancer cells can hide from the immune system or suppress its response.
Through immunotherapy, your body can be equipped to better recognize and destroy cancer cells, ultimately helping to slow down or stop the growth of cancer in your body. This type of treatment has shown promising results in certain types of cancers, offering new hope for patients and their families.
In essence, immunotherapy works by enhancing your body’s natural defense mechanisms to target cancer cells specifically. It is a revolutionary approach to cancer treatment that offers a more targeted and personalized way to combat this disease. By understanding how immunotherapy works, you can better grasp its potential benefits and impact on cancer treatment.
Types of Immunotherapy
There are three main types of immunotherapy treatments that have proven to be effective in helping the body’s immune system fight cancer:
Checkpoint Inhibitors
- Checkpoint inhibitors help the immune system recognize and attack cancer cells by blocking proteins that prevent immune cells from recognizing and targeting cancer.
- Common checkpoint inhibitors include drugs like pembrolizumab (Keytruda) and nivolumab (Opdivo).
Monoclonal Antibodies
- Monoclonal antibodies are laboratory-made proteins that attach to specific targets on cancer cells, stimulating the immune system to attack these cells.
- Trastuzumab (Herceptin) and rituximab (Rituxan) are examples of monoclonal antibodies used in cancer treatment.
Adoptive Cell Therapy is another approach that involves genetically modifying a patient’s own T cells to better recognize and attack cancer cells.
Understanding the different types of immunotherapy available can help patients and healthcare providers make informed decisions about the best treatment options for individual cancer types and stages. It is essential to consult with a healthcare professional to determine the most suitable immunotherapy treatment for each specific case.
Monoclonal Antibody Therapy
Monoclonal antibody therapy is a type of immunotherapy that uses antibodies made in a lab to target specific antigens on cancer cells. These antibodies work by attaching to the antigens and helping the immune system to identify and destroy the cancer cells. This targeted approach can help reduce the side effects often seen with traditional treatments like chemotherapy.
One key benefit of monoclonal antibody therapy is its ability to specifically target cancer cells, leaving healthy cells unharmed. This targeted approach can lead to fewer side effects and a better quality of life for patients undergoing treatment. Additionally, monoclonal antibody therapy can be used in combination with other treatments, such as chemotherapy or radiation therapy, to enhance their effectiveness.
It is important to note that monoclonal antibody therapy is not suitable for all types of cancer, and its effectiveness can vary depending on the specific type of cancer being treated. It is crucial for patients to work closely with their healthcare team to determine the best treatment plan for their individual needs.
In conclusion, monoclonal antibody therapy is a valuable tool in the fight against cancer, offering a targeted approach with potentially fewer side effects than traditional treatments. Patients should discuss with their healthcare team whether monoclonal antibody therapy is a suitable option for their specific type of cancer.
Checkpoint Inhibitors
Checkpoint inhibitors are a type of immunotherapy that work by blocking proteins that prevent the immune system from attacking cancer cells. By targeting these proteins, checkpoint inhibitors help the immune system recognize and destroy cancer cells more effectively.
Some common checkpoint inhibitors include pembrolizumab, nivolumab, and ipilimumab. These drugs have shown promising results in treating a variety of cancers, including melanoma, lung cancer, and bladder cancer.
It is important to note that checkpoint inhibitors can cause side effects, as they activate the immune system to attack cancer cells. These side effects may include fatigue, skin rash, or gastrointestinal issues. It is crucial to communicate any side effects to your healthcare provider promptly.
Checkpoint inhibitors are typically used in combination with other cancer treatments, such as chemotherapy or radiation therapy, to maximize their effectiveness. Your healthcare provider will determine the best treatment plan for your specific type and stage of cancer.

Adoptive Cell Therapy
Adoptive cell therapy is a form of immunotherapy that involves reprogramming a patient’s own immune cells to recognize and attack cancer cells. This personalized approach harnesses the power of the body’s own immune system to target and destroy cancer cells effectively.
One common type of adoptive cell therapy is CAR-T cell therapy, where T cells are genetically modified to express chimeric antigen receptors (CARs) that can recognize specific antigens on cancer cells. These engineered T cells are then infused back into the patient to seek out and destroy cancer cells.
Another form of adoptive cell therapy involves using tumor-infiltrating lymphocytes (TILs), which are immune cells that have naturally infiltrated a tumor. These TILs are isolated from the tumor, expanded in the lab, and reintroduced into the patient to target the cancer cells.
Adoptive cell therapy has shown promising results in treating certain types of cancer, with some patients achieving long-lasting remissions. However, it is important to note that this treatment approach is still being researched and refined, and not all patients may benefit from it. Consulting with a healthcare provider who specializes in immunotherapy is essential to determine if adoptive cell therapy is a suitable option for individual patients.
How Immunotherapy Works
Immunotherapy works by using the body’s own immune system to fight against cancer cells. This type of treatment helps to boost the immune system’s natural ability to recognize and destroy cancer cells. There are three main types of immunotherapy: checkpoint inhibitors, CAR T-cell therapy, and cancer vaccines.
Checkpoint inhibitors work by blocking proteins that prevent the immune system from attacking cancer cells. This allows the immune system to recognize and destroy the cancer cells more effectively. CAR T-cell therapy involves modifying a patient’s T-cells in a laboratory to better target and kill cancer cells. Cancer vaccines help to stimulate the immune system to recognize and destroy cancer cells.
Overall, immunotherapy is a promising approach to treating cancer as it harnesses the body’s own defenses to fight the disease. It is important to consult with a healthcare provider to determine if immunotherapy is a suitable treatment option for a specific type of cancer.
Side Effects of Immunotherapy
It is important to note that while immunotherapy has revolutionized cancer treatment, it is not without its side effects. These side effects can vary depending on the type of immunotherapy being used and the individual’s unique response to treatment.
Common Side Effects
Some common side effects of immunotherapy include fatigue, skin reactions, flu-like symptoms, and digestive issues. It is crucial to communicate any side effects to your healthcare team so they can provide the necessary support and adjustments to your treatment plan.
