Summary: Cancer is one of the world's biggest killers, and current treatments often have terrible side effects. So scientists have begun looking into ways to help the body's own defenses fight back. When have a bacterial or viral infection, our immune systems go into overdrive to tackle the invader and protect our bodies. If it were possible to harness this line of attack and use it against cancer, this could open up a whole new method of treating the disease. At the British Science Festival, Ginny Smith talked to Louise and Vanessa, both PhD students at Birmingham University, about their research on using our own immune systems to fight cancer.
