Scientists may have found a way to harness the immune system and strike at hidden tumors throughout the body. By boosting the body's own immune system it may be able to mount a body-wide assault on cancer cells. Animal tests suggest that a treatment given to just one tumor produces an immune response that targets secondary growths in other places. Researchers from Chicago University now hope the same effect can be reproduced in humans with cancer.
