Immunotherapy Cancer Treatment: Can our body fight cancer on its own? Learn how immunotherapy works and when it is effective.

News Topical, Digital Desk : Cancer is a common disease these days. Many types of therapies are used to treat it. Meanwhile, immunotherapy has emerged as a new hope in cancer treatment. Instead of directly attacking the cancer, this treatment helps fight cancer cells by strengthening the body's immune system. However, doctors say it is not uniformly effective across patients. So, let's explore whether our bodies can fight cancer on their own, how immunotherapy works, and when it is effective.

What is immunotherapy?

Immunotherapy is a cancer treatment that activates the body's immune system. Normally, the immune system recognizes and destroys malignant or abnormal cells. However, cancer cells have the ability to hide or weaken the immune system. This therapy works to remove these barriers. It involves drugs like checkpoint inhibitors, which release the brakes on immune cells, enabling them to attack cancer cells.

How does immunotherapy work inside the body?

T cells in the immune system recognize and destroy cancer cells. However, cancer cells sometimes send signals that confuse these T cells. Immunotherapy improves this process. It helps T cells recognize cancer, strengthens the immune response, and blocks signals that prevent attack. Doctors say this treatment has shown long-term benefits in some patients. In many cases, its effects persist even after treatment is stopped. Its side effects may also be milder than those of chemotherapy.

Why does it not affect every patient?

Experts say that immunotherapy doesn't work for everyone. This is due to several reasons, including some tumors lacking the necessary T cells, cancer cells' ability to hide their identity, the creation of an environment in the body that suppresses the immune system, and the rapid growth of the cancer itself.

Benefits of Immunotherapy

According to doctors, immunotherapy has several advantages, including long-term effectiveness in some cases. It is considered a more targeted treatment and may be an option for advanced cancer. However, it also has some risks. It can affect healthy body parts, causing problems like skin rashes, fatigue, or swelling in the limbs. In severe cases, immediate treatment may be required.

When is this immunotherapy given?

According to doctors, this treatment is not offered to every patient. Several factors are taken into account, such as the type and stage of the cancer, specific biomarkers present in the body, the patient's overall health, and previous treatments, to determine whether immunotherapy should be administered. Doctors also say that sometimes immunotherapy alone is not effective, so it is combined with other treatments, such as chemotherapy or targeted therapy, to achieve optimal results.
