Before we dive deeper into the concept of immunotherapy, it’s essential for us to know what the immune system is and what it does.
The immune system is a collection of special cells, organs, and substance that protects the body from infections and diseases. These special immune cells and the substances that they make travel across the body via the bloodstream and protect the body from infection-causing germs.
The immune system keeps track of all the naturally found substances in the body. When a foreign substance enters the body, the immune system recognizes it and launches an attack against it as a response. The main aim of this immune response is to destroy these foreign substances and keep the body healthy.
However, in the case of cancer cells, the immune system has a hard time targeting them because cancer starts when normal cells get altered and start growing out of control. So the immune system has a hard time recognizing these cells as foreign.
People with healthy immune systems might still develop cancer because there are limitations on the immune system’s ability to fight cancer alone. Sometimes the immune system might not recognize cancer cells as foreign, sometimes the response might not be strong enough and sometimes the cancer cells themselves give off substances that might keep the immune system from finding them.
Amidst all these loopholes, researchers have found a solution in the form of Immunotherapy that can help the immune system recognize these cancer cells and strengthen its response against them.
Immunotherapy is the treatment that uses a person’s immune system to fight diseases like cancer. It does so by:
- Boosting the natural defense of the immune system
- Makin substances that are similar to immune system components and use them to restore the immune system’s attacks against the cancer cells
Immunotherapy is an effective therapy of cancer treatment where the body’s natural defenses are boosted that enables the body to fight off cancer. Immunotherapy works by stopping the growth of cancer cells or slows their growth. As compared to chemotherapy and radiation, immunotherapy has the least known reactions and side effects. This novel line of treatment involves one’s own immunity to stay healthy rather than depending on other drugs and medicines.
Immunity can be strengthened through a number of ways like eating right, having the right routine, appropriate physical activities, mental well being and by taking immune boosters. Apart from all this, immunotherapy drugs can help in the production of specific agents in the immune system that fights out specific diseases.
