Cancer Research UK is the Worlds leading charity dedicated to beating cancer through research. Our groundbreaking work into the prevention, diagnosis and treatment of cancer has helped save millions of lives. Survival rates have doubled in the last thirty years and we have been at the heart of that progress. But one in three of us will still get cancer at some point and our vital work, funded entirely by the public, will help ensure that millions more people will survive.
