Ralph W. Moss, PhD, has been thinking and writing about cancer — especially its less-conventional treatments — for over 35 years. During this time he has written or edited twelve books and three film documentaries on questions relating to cancer research and treatment. Moss is a graduate of New York University (BA, cum laude, Phi Beta Kappa, 1965) and Stanford University (MA, 1973, PhD, 1974, Classics).

The former science writer and assistant director of public affairs at Memorial Sloan-Kettering Cancer Center in New York (1974-1977), Moss evaluates the claims of various conventional and non-conventional cancer treatments. He currently directs The Moss Reports, an up-to-date library of detailed reports on more than 200 varieties of cancer. Since 2001 he has published a weekly online newsletter that reaches tens of thousands of readers. Although not a medical doctor, he is noted for his critical acumen on health topics and is listed in Marquis Who’s Who in America, Who’s Who in the World, Who’s Who in HealthCare, etc.

Moss is the author of such books as Antioxidants Against Cancer, Cancer Therapy, Questioning Chemotherapy, and The Cancer Industry, as well as the award-winning PBS documentary The Cancer War. He also wrote the first article on alternative medicine for The Encyclopedia Britannica yearbook and the first article on complementary cancer treatments for a medico-legal textbook, Courtroom Medicine: Cancer. With Prof. Josef Beuth of Cologne, he co-edited the first medical textbook in English on non-conventional treatments for cancer, Complementary Oncology (2005).

His articles and scientific communications have appeared in such journals as The Lancet, the Journal of the National Cancer Institute, the Journal of the American Medical Association, New Scientist, Anticancer Research, Genetic Engineering News, Research in Complementary Medicine (Karger), the Journal of Alternative and Complementary Medicine, and Integrative Cancer Therapies (SAGE), of which he is Corresponding Editor.

  1. Hi Dr. Moss,

    What are your thoughts on Poly MVA for Stage 1 Breast Ca., triple negative? Thx.


  2. Which method would you suggest for getting rid of a cancerous liver tumor: chemo radiation done through a tube inserted at the top of the thigh or a liver transplant?

  3. Hi In your last newsletter you mentioned that the tolerable intake of organic iodine is 1100 mcg
    Inorganic iodide and iodine many times that amount are used in products like SSKI, Lugols, Iodoral, etc with no adverse effects or autoimmune responses.
    Your comments?

  4. I hate blogs! I never know how to download them and waste a lot of time! I like email. I can download it and read it when I have time. Wanted to learn more about Breast Defend. Want to know how it compare ingredients with what I am taking for breast cancer metasiacised to bone. It regressed but not totally withQi Gong, accupuncture, supplements and,and mistletoe and complex homeopathics from Paracelsus Klinik [Paracelsus.ch] in Swiotzerland. Paula Velsey

  5. Neglected to add to message I just sent that I have been on 2 different Chemos [Xeloda last Dec, then Vinorelbine/Navelbine for 1 month] in addition to alternative treatments. Paula Velsey

  6. Have you any opinion on lowdosenaltrexone as part of the treatment regime for cancer. There is a website at http://www.lowdosenaltrexone.org.

  7. with the recent pulling of Avastin, as a treatment modality, for breast cancer; is it also contraindicated for the other types of cancers that it is being used for? I say yes, but of course. Unfortunately the recent reports are not including it contraindicated for treatment of lung and colon cancer. What is the thought here?

    • No, it has not been disapproved for other indications, only breast. RWM
