ABSTRACT
Ruth focused her efforts on the genetics of cancer during her final 25 years. “I had really wanted to work on cancer, but it seemed like a very difficult thing to do.’ Entry into the subject was by her sabbatical at the Imperial Cancer Research Fund in 197273. “We think that the first change in cancer is a genetic change — something acts to transform an individual cell-whether that something be a viral infection, or a chemical or radiation”.
