Immunotherapy, which is also called biologic therapy, is a type of cancer treatment that improves the body's natural defenses to fight cancer. It uses substances produces naturally by the body or in a laboratory to enhance and make the immune system work better. The doctor might recommend immunotherapy as the only treatment for cancer sometimes, or it might be accompanied with other types of treatment mainly chemotherapy, radiation therapy and surgery to beat certain kind of cancer. Certain types of immunotherapy fight against cancer and slow down its spread to other organs of the body. Others make your immune system more strong to damage the cancer cells. Immunotherapy sometimes causes the immune system to attack healthy cells, which can lead to several side effects.
Side effects of immunotherapy vary from being mild to moderate, or even life-threatening at times. Depending on the severity of your side effects, the doctor might stop the cancer treatment or prescribe certain medications. If side effects worsen or do not improve, the doctor might have to stop immunotherapy. Different people have different side effects. The side effects you have and how they make you feel totally depends on how healthy you are before the treatment, your type of cancer, the stage of your cancer, the type of immunotherapy you are getting, and the dosage.
