After the death of his wife from ovarian cancer, Maurice Saatchi felt crushed by the ‘medieval’ treatment that cancer patients must endure. It drove him to launch a Private Member’s Bill in the House of Lords, which seeks to promote medical innovation and reduce doctors’ fear of litigation in the event of something going wrong. This change could save lives. But is it right to give doctors license to experiment on their patients with unapproved treatments, even if they have the best of intentions? Is the distinction between responsible innovation and reckless experimentation so easily made? Lord Saatchi is joined by Dame Gail Rebuck who recently lost her husband to cancer, Professor Ara Darzi, Paul Hamlyn Chair of Surgery at Imperial College London, and medical ethicist Deborah Bowman to discuss the challenges a Bill like this faces.
