Our body’s natural immune system is able to protect the body from infection against bacteria and viruses. However, when the immune system is not strong enough to mount a defense or when the immune cells do not recognize cancer cells as ‘foreign’, the cancer remains undetected and is free to grow and spread.
Immunotherapy is a kind of cancer treatment that activates the patient’s immune system’s natural cancer-fighting abilities. Immunotherapy aims to trigger our immune system’s natural abilities to fight off cancer.
