This week Kat Arney joins us live from the National Cancer Research Institute's conference in Liverpool. We find out how mistakes in cell signalling can cause cancers and why DNA repair pathways offer targets to treat tumours. Also, we explore the latest developments in cancer imaging, including new techniques that allow us to track chemical reactions happening inside the body. In the news, why you need to remove genes to repair nerves, and how clearing out old cells can prevent diseases of old age! Like this podcast? Please help us by supporting the Naked Scientists)
