Activating the immune system for therapeutic benefit in cancer has emerged as one of the most promising developments in immunology and oncology. In the past few decades, scientists have been trying to manipulate the human immune system to attack cancer cells. It's called immune therapy (or immunotherapy) and it works by harnessing the body's own natural killing cells to kill tumours. Cancer Immunotherapy has become a key part of treatment for many different types of the cancer.

How Immunotherapy Works Against Cancer


The immune system monitors all of the substances normally found in the body. Any new foreign substance that the immune system doesn’t recognize raises an alarm, causing the immune system to attack and kill it. However immune system has a tougher time targeting cancer cells because they are able to hide from your immune system and multiply rapidly.  To overcome this, researchers have found ways to help the immune system to mark and destroy these cells. as emerged as what many in the cancer community now call the “fifth pillar” of cancer 

Types of Cancer immunotherapy


The main types of immunotherapy currently used to treat cancer include:


Monoclonal Antibodies


These are man-made versions of immune system that bind to specific antigens on cancer cells.  They have been designed as one of the most successful therapeutic strategies for both hematologic malignancies and solid tumors.


T-cell Therapy


Chimeric antigen receptor (CAR) T-cell therapy has been restricted to small clinical trials, largely in patients with advanced blood cancers. It requires drawing blood from cancer patient’s blood, and genetically altering them in a lab to produce specific receptors known as chimeric receptors so they can seek out and kill cancer cells.


Immune Checkpoint Inhibitors


Checkpoint inhibitors are currently the most generally utilized type of immunotherapy. They obstruct the activity of inhibitory molecules or enact stimulatory molecules which are found on the surface of numerous T cells. They are infused into the blood where they find the body's natural cancer-killing immune cells and keep them switched on so they can attack tumours. 


cytokines are often given in combination with chemotherapy or radiotherapy to promote tumor immunity, inflammation, and carcinogenesis. These are of two types interleukins, which speed up the division of immune cells, and interferon’s, which helps the body in resisting cancer.

Cancer Vaccines

Cancer treatment vaccines are designed to treat cancers that have already been developed by strengthening the body’s immune system against the cancer. They are made from a patient’s own tumor cells by building up antibodies without actually contracting the illness.
