The expression "a life dedicated to science" may seem a bit over the top for many, but it's spot on for German cancer researcher and Nobel laureate Harald zur Hausen. In the 1970s he first voiced his hypothesis that viruses could cause cancer, only to be mocked by older colleagues.
But his tenacity and single-mindedness saw him succeed in demonstrating the link between strains of the human papilloma virus (HPV) and cervical cancer. Now a vaccine has been developed to prevent women from contracting the disease. Tomorrow Today talks to the Nobel laureate and long-time researcher at the German Cancer Research Center, the DKFZ.
