The idea of defeating cancer with your own defense system is not new, and urology expert, Dr. David Samadi discusses immunotherapy in several articles, posted on his Samadimd.com blog. New drugs release the invisibility cloak of the cancer cells, making them vulnerable to the immune system, and Dr. Samadi says this may be an opportunity, especially in advanced cancer that was previously considered no longer curable.

What Is Immunotherapy?
The underlying concept of this approach is to boost the immune system to respond appropriately to the presence of a foreign agents such as cancer. Cancer cells have the ability to multiply uncontrollably – and unnoticed by the immune system – while destroying healthy tissue. Using targeted treatments or immunotherapy, it activates the body’s defenses so that the immune system itself can attack the tumor cells.
Dr. Samadi explains that there are variants of immunotherapy;
1. Some tumors have developed the ability to escape the immune system. Cancer cells can multiply uncontrollably. The infusion of so-called checkpoint inhibitors re-activates the immune system, recognizing the cancer cell as an enemy and attacking it.
2. Messengers of the immune system (cytokines) are directed into the body. These then activate cells of the immune system that attack and destroy tumor cells.
3. Patients’ cancer cells are modified and re-administered in the laboratory – this trains their own immune system to accurately detect tumors and attack them directly.
Which Cancers Do Immunotherapy Work?
So far, patients with malignant melanoma, certain forms of lung cancer, tumors in the bladder and kidney, tumors in the head and neck, Merkel cell carcinoma, Hodgkin’s lymphoma and multiple myeloma can be treated with immunotherapy. Successes have so far been recorded, especially in advanced cancer stages.
Dr. Samadi says that studies show that the survival time of patients with lung cancer increased by several months, and in patients with melanoma skin cancer, by several years. In addition to surgery, chemotherapy and radiation, immunotherapy is a exciting weapon against cancer.
