When anyone learns that they have cancer, they are very scared and feel a great burden on their heart. It is very normal. But with the advancement of medical science, there are now many new and advanced treatments to fight cancer. You may have heard the word 'immunotherapy' before. This is a relatively modern treatment that has brought new hope to many people in the fight against cancer. So, let's talk about this in a little more detail today, in a way that everyone can understand.
Simply put, what is immunotherapy?
To understand this, we first need to understand the amazing defense system that our bodies have. That is the immune system . Like an army that protects a country, this system protects us from disease by fighting germs, such as bacteria and viruses, that enter our bodies.
Normally, this immune system can identify and destroy abnormal cells in the body, even cancer cells. However, cancer cells are a very cunning type of cell. Sometimes they use various tricks to hide from our immune system. Or they can weaken the immune system.
This is where immunotherapy comes in. Simply put, immunotherapy works by reviving our dormant defenses, the immune system, and telling them, "Hey, there are cancer cells lurking here, let's find them and destroy them." This is done by giving the body things like special proteins (cytokines) that help cells communicate with each other, or by giving drugs that help immune cells recognize cancer cells more easily.
What are the benefits of immunotherapy?
There are several specific reasons why this treatment method is popular among cancer patients. Let's take a look at the main advantages.
| Benefit | Simple Explanation |
|---|---|
| Successful even in cancers that do not respond to other treatments | Immunotherapies have been able to control some stubborn types of cancer that do not respond well to traditional treatments such as chemotherapy or radiotherapy. |
| Relatively low side effects | Treatments like chemotherapy can also damage healthy cells, so side effects like hair loss and severe nausea are common. But because immunotherapy targets the immune system, such serious side effects are relatively rare. |
| Getting long-term protection | This is one of the most important advantages of this treatment. The immune system has a 'memory'. Once it learns to recognize cancer cells through immunotherapy, the system remembers those cells. Therefore, the risk of cancer recurrence in the future is reduced. |
| Can be used for various types of cancer | This method is already being used to treat nearly 20 types of cancer. As research is still ongoing, it is hoped that this will be a successful treatment for many more types of cancer in the future. |
Let's also be aware of the risks and disadvantages of this treatment.
As with any treatment, immunotherapy has its own risks and benefits, and it's important to be aware of these.
| Risk / Disadvantage | Description |
|---|---|
| Not everyone gets the same results. | This treatment may be successful for one patient, but not for another. Also, while it works well for some types of cancer, it may not be as effective for others. |
| High cost | Because this is a modern technology, and because the treatment sometimes has to be tailored to each patient, the cost of treatment is relatively high. |
| Possibility of side effects | Some side effects can occur due to an over-reaction of the immune system. Headaches, body aches, fatigue, nausea, skin rashes, and fever are common. The important thing is that these can be managed well if they are recognized and reported to a doctor early. |
| Affecting healthy cells | Very rarely, an overactive immune system can attack healthy organs in the body (e.g., lungs, liver, skin, intestines) as well as cancer cells. This can be a dangerous condition, so it is essential to remain under medical supervision throughout treatment. |
So, how do I decide if this treatment is right for me?
This is the most important question. This is not a decision you can make alone. Whether immunotherapy is right for you should be decided after careful discussion with your treating oncologist , who is best acquainted with your condition.
Your doctor will consider several factors when making this decision:
- The type of cancer you have.
- The stage at which the cancer has spread.
- Your overall health.
- Treatments you have received previously.
- Some specific genetic markers (specific genetic mutations ) in your cancer cells.
Every cancer patient and every cancer is different. Therefore, a treatment that works for one person may not work for another. Therefore, it is very important to follow your doctor's instructions exactly.
If you have any questions about this, don't hesitate to ask your doctor. Don't be afraid to ask questions like, "Doctor, is immunotherapy a good option for my condition?" or "What side effects might this cause?"
Take-Home Message
- Immunotherapy is a modern treatment method that uses our own body's defense system ( immune system ) to destroy cancer cells.
- This treatment has both advantages and disadvantages. The main advantages are fewer side effects and longer-term safety compared to chemotherapy.
- The disadvantages and risks include high cost, inconsistent results for all patients, and the risk of over-reacting the immune system.
- Side effects are possible, but they can be well controlled if they are recognized early and medical advice is sought.
- You should only decide whether this treatment is right for you after discussing it with your oncologist. Never make decisions based solely on the experiences of others.
