Documentary following pioneering surgeons at Royal Marsden Hospital as they face some of the most complex and challenging oncological cases in the world. In the first episode, a surgical robot is used to treat a tumour on a patient's voice box, in a procedure that has never been attempted before. Other surgeons must perform a complex procedure to try to save a photographer's arm, and remove new cancer growth in a patient's abdomen.
