Immunotherapy is a biological treatment that can strengthen the body’s immune system to help it identify and destroy foreign invaders, such as infection-causing viruses, bacteria and toxins. Through extensive research, scientists have discovered that the body’s natural defense mechanisms can also recognize and target cancerous cells. However, the immune system’s ability to fight cancer on its own is limited for several reasons.
Cancer develops when healthy cells undergo abnormal changes. In some cases, the immune system cannot distinguish between cancerous cells and normal cells because they are not that different. In other cases, the immune system recognizes the cancerous cells but its response is not strong enough to destroy them. Finally, some cancerous cells have unique characteristics that allow them to evade detection by the immune system.
To overcome these challenges, scientists have developed immunotherapies to help the immune system identify cancerous cells and intensify its response to them.
