Interferon alpha is a man-made copy of a substance that some types of white blood cell make naturally in the body. Blood cells make interferon as part of an immune response when the body reacts to infection or cancer. Giving interferon may stimulate the body to fight the cancer. Not many people can tolerate this treatment due to the strong side-effects and it is rarely given as a treatment now. It is not recommended by NICE.
