Panorama reports on the cancer patients who are pioneering a new generation of drug treatments. Patients given just months to live are keeping the disease at bay for years; for some there is even talk of a cure. More than one in three of us will develop cancer, but huge advances in genetics are transforming our understanding of the disease and how to combat it. Panorama was given unprecedented access to trials at the Royal Marsden and Institute of Cancer Research and talked to patients old and young as well as their families and medical teams.
