Preventing Breast Cancer

Do Mammograms cause cancer? John Gofman thinks so. Who is John Gofman?

John Gofman, M.D., Ph.D., Professor Emeritus of Molecular and Cell Biology at UC Berkeley, Lecturer at the Department of Medicine, University of California School of Medicine at San Francisco, and founder and former associate director of the Lawrence Livermore National Laboratory for Biomedicine.

He is the author of several books and more than a hundred scientific papers in peer-review journals in the fields of nuclear / physical chemistry, coronary heart disease, ultracentrifugal analysis of the serum lipoproteins, the relationship of human chromosomes to cancer, and the biological effects of radiation, with especial reference to causation of cancer and hereditary injury.

He is the author of the book, Preventing Breast Cancer, which in now available to read or download for free on line. This book uncovers the major cause of the recent breast-cancer incidence in the USA. The author shows that past exposure to ionizing radiation --- primarily medical x-rays --- is responsible for about 75 percent of the breast-cancer problem in the United States.
The good news: Since the radiation dosage given today by medical procedures can be significantly reduced without interfering with a single useful procedure, numerous future cases of breast-cancer can be prevented.
The author recommends specific actions to start breast-cancer prevention now, not ten years from now. If you or someone you know are at risk for breast cancer, it is imperative that you read this book, Preventing Breast Cancer. Originally published in 1992 and revised in 1996. That is over 10 years ago!

A Narrative Chronology

          While a graduate student at Berkeley, Gofman co-discovered protactinium-232, uranium-232, protactinium-233, and uranium-233, and proved the slow and fast neutron fissionability of uranium-233.

          Post-doctorally, he continued work related to the chemistry of plutonium and the atomic bomb development. At that early period, less than a quarter of a milligram of plutonium-239 existed, but a half-milligram was urgently needed for physical measurements in the Manhattan Project. At the request of J. Robert Oppenheimer, Gofman and Robert Connick irradiated a ton of uranyl nitrate by placing it around the Berkeley cyclotron (to capture neutrons), for a total exposure period of six weeks, with operation night and day. In 110 Gilman Hall, they scaled up Gofman's previous test-tube-sized sodium uranyl acetate process for the plutonium's chemical extraction. Dissolving 10-pound batches of the "hot" ton in big Pyrex jars, and working around the clock with the help of eight or ten others, they reduced the ton to a half cc of liquid containing 1.2 milligrams of plutonium (twice as much as expected).

          After the plutonium work, Gofman completed medical school. In 1947, he began his research on coronary heart disease and, by developing special flotation ultracentrifugal techniques, he and his colleagues demonstrated the existence of diverse low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Their work on lipoprotein chemistry and health consequences included the first prospective studies demonstrating that high LDL levels represent a risk-factor for coronary heart disease and that low HDL levels represent a risk-factor for coronary heart disease. His principal book on the heart disease research is Coronary Heart Disease (1959, Charles C. Thomas, Publisher).

          In the early 1960s, the Atomic Energy Commission (AEC) asked him if he would establish a Biomedical Research Division at the Lawrence Livermore National Laboratory, for the purpose of evaluating the health effects of all types of nuclear activities. From 1963-1965, he served as the division's first director, concurrently with service as an Associate Director of the entire Laboratory, for Biomedicine. Later he stepped down from these administrative activities in order to have more time for his own laboratory research in cancer, chromosomes, and radiation, as well as his analytical work on the data from the Japanese atomic-bomb survivors and other irradiated human populations.

          In 1965, Dr. Ian MacKenzie published an elegant report entitled "Breast Cancer Following Multiple Fluoroscopies" (British J. of Cancer 19: 1-8) and in 1968, Wanebo and co-workers, stimulated by MacKenzie's work, reported on "Breast Cancer after Exposure to the Atomic Bombings of Hiroshima and Nagasaki" (New England J. of Medicine 279:667-671), but few were willing to concede that breast-cancer could be induced by low-LET radiation.

          Gofman and his colleague, Dr. Arthur Tamplin, quantified the breast-cancer risk (1970, The Lancet 1:297), looked at the other available evidence, and concluded overall that human exposure to ionizing radiation was much more serious than previously recognized (Gofman 1969; Gofman 1971).

          Because of this finding, Gofman and Tamplin spoke out publicly in favor of re-examining two programs which they had previously accepted. One was the AEC's "Project Plowshare," a program to use hundreds or thousands of nuclear explosions to liberate natural gas in the Rocky Mountains and to excavate harbors and canals. Experimental shots had already been done, for example, in Colorado and Nevada. The second program was the AEC's plan to license about 1,000 nuclear power plants as quickly as possible and to build a "plutonium economy" based on breeder reactors. In 1970, Gofman and Tamplin proposed a five-year moratorium on licensing of commercial nuclear power plants.

          For Gofman and Tamplin, the public health was the issue of prime importance. The Atomic Energy Commission was not pleased. In 1973, Gofman returned to full-time teaching at the University of California at Berkeley, until choosing an early and active "retirement" --- a retirement to full-time research on radiation health-effects. This research led to publication of four scientific books, and to the current work, Preventing Breast Cancer. The previous books are:

  1. Radiation And Human Health, 908 pages (1981).

  2. X-Rays: Health Effects of Common Exams (with Egan O'Connor), 439 pages (1985).

  3. Radiation-Induced Cancer From Low-Dose Exposure: A Independent Analysis, 480 pages (1990).

  4. Chernobyl Accident: Radiation Consequences for This and Future Generations, 574 pages (1994). It is in the Russian language. An English-language edition will be published in the future.
