Immunotherapy
Treatments that use the body's immune system to fight cancer.
What it is
Immunotherapy is a type of cancer treatment that uses the body's immune system to fight cancer. It works by helping the immune system recognize and attack cancer cells, which are often hidden from the immune system. This can be done through various methods, such as using medications that stimulate the immune system or removing certain cells that suppress it.
How it works
Immunotherapy can work in different ways, depending on the type of treatment. Some immunotherapies, called checkpoint inhibitors, release the brakes on the immune system, allowing it to attack cancer cells more effectively. Other immunotherapies, called cancer vaccines, help the immune system learn to recognize and attack cancer cells. In some cases, immunotherapy may be used in combination with other treatments, such as surgery or chemotherapy.
Why it matters
Understanding immunotherapy is important for patients and carers because it may offer new treatment options for certain types of cancer. Immunotherapy can be particularly effective for cancers that are difficult to treat with other methods, such as melanoma or lung cancer. Researchers are also studying immunotherapy to see if it can be used to prevent cancer from coming back after treatment.
