Stat reported that in 2017, Richard Graydon self-published a book titled The Genetic Risks of Cancer: The Effects of DNA, Genomics and Inheritance on Aging and Survival.” The book described Graydon as an oncologist who had served as a chief medical officer in the biotech and drug development industry.
