Immunotherapy for cancer
Immunotherapy uses treatments that work with the immune system to help the body fight cancer. These treatments may slow or stop the growth of cancer cells or keep cancer from spreading. Or they may help the immune system kill cancer cells.
Types of immunotherapy include immune cell therapies, cancer vaccines, and medicines such as checkpoint inhibitors.
What are some types of immunotherapy for cancer?
Immunotherapy helps treat cancer by supporting the body's immune system. This type of treatment can restore, boost, or redirect the immune system.
Immunotherapy for cancer includes:
- Medicines.
-
These include cytokines and monoclonal antibodies. Cytokines are proteins made by the immune system to help cells communicate. Monoclonal antibodies find a certain protein on the surface of some cells. They lock onto it (like a key in a lock). This may then trigger the body's immune system to attack and destroy those cells.
- Immune cell therapies.
-
One example is CAR T-cell therapy. A person's T cells are treated in a lab so the T cells are more able to attack cancer cells.
- Vaccines.
-
Treatment vaccines, such as Sipuleucel-T, help the body's immune system find and attack cancer cells.

What are some questions to ask your doctor about immunotherapy for cancer?
Here are some questions to ask:
- How long has it been used to treat cancer like mine?
- How will this treatment help me?
- What happens during the treatment? How long will it take? How often and where do I get it?
- What are the side effects?
