Immunotherapy is a type of cancer treatment that uses the body’s own immune system to fight cancer cells. There are two main types of immunotherapy, active or passive.
Active immunotherapy uses substances to stimulate the immune system to attack cancer cells. This can be done with vaccines, antibodies, or other substances.
Passive immunotherapy uses substances that have already been produced by the immune system to attack cancer cells. This can be done with antibodies or other substances.
Immunotherapy has been shown to be effective in the treatment of many different types of cancer, including melanoma, lung cancer, and bladder cancer. It is also being studied for the treatment of other types of cancer, such as breast cancer and prostate cancer.
