What is immunotherapy?

Immunotherapy is a type of cancer treatment (drug) that uses your body’s own immune system to fight cancer cells. Your immune system fights infections and diseases.

How does immunotherapy work?

Immunotherapy makes your immune system stronger at fighting cancer cells. Your immune system becomes better at finding and attacking cancer cells. Immunotherapy can continue to fight your cancer even after your treatment ends. This can sometimes lead to long-term control of your cancer.
