'We're better at treating cancer the earlier we detect it,' top specialist says

One of the world’s leading cancer specialists has spoken to FRANCE 24 about the need to detect cancer early and prevent it from ever taking hold, rather than having to treat people later. Professor Alexandra Leary is an oncology specialist in gynaecological cancers and deputy director of the oncological department of the Gustave Roussy cancer research hospital outside Paris. She is just back from a major gathering of the world's top cancer specialists in Chicago. She spoke to us in Perspective.
