Ralph W. Moss, PhD 


The medical writer Ralph W. Moss, PhD, has written or edited twelve books and four film documentaries on questions relating to cancer research and treatment.

Dr. Moss is a graduate of New York University (BA, cum laude, Phi Beta Kappa, 1965) and Stanford University (MA, 1973, PhD, 1974, Classics). He is the former science writer and assistant director of public affairs at Memorial Sloan-Kettering Cancer Center in New York (1974-1977). Since leaving Sloan-Kettering in 1977, Moss has independently evaluated the claims of conventional and non-conventional cancer treatments all over the world.

He currently writes Moss Reports, detailed reports on the most common cancer diagnoses and provides informational and personalized consultations for cancer patients and their families. In 2019, he wrote The Ultimate Guide to Cancer: DIY Research, to help lay people research their own cancers. This 50-page report is available free of charge at the website.


Dr. Moss has made site visits to cancer clinics in Belgium, China, Germany, Mexico, Holland, Austria, Hungary, Ireland, Israel, the Czech Republic, Russia, Switzerland, Denmark, Italy, Bahamas, Honduras, Great Britain, and most states of the US and provinces of Canada. He continues to tour clinics around the US and the world looking for advanced cancer treatments for his phone consultees and for readers of his blog, magazine columns and Moss Reports.


Many of Dr. Moss’ books are now out of print (OOP), and in some cases the information they contain may be somewhat out of date as scientific advances and additional research is done. See our Books section for downloadable eBooks by Ralph W. Moss, PhD.
