FOR IMMEDIATE RELEASE
Food & Drug Administration Admits Medical Radiation Risks, Ignores Mammography Dangers
CHICAGO, IL, February 16, 2010 --/WORLD-WIRE/-- The Cancer Prevention Coalition notes with approval that on February 9, the Food and Drug Administration announced that it would take stringent action to regulate "the most potent forms of medical radiation," particularly those from increasingly popular CT scans.
Cancer Prevention Coalition Chairman Samuel S. Epstein, M.D. commends the FDA for warning that such radiation is unsafe and equivalent to that of about 400 chest X-rays, 0.4 rads (radiation absorbed dose), and "can increase a person's lifetime cancer risk."
However, says Dr. Epstein, "the FDA remains strangely unaware that radiation from routine premenopausal mammography poses significant and cumulative risks of breast cancer."
This warning is contrary to conventional assurances that radiation exposure from mammography is trivial, about 1/1,000 of a rad, and similar to just that from a chest X-ray. However, Dr. Epstein explains, the routine practice of taking two films of each breast results in exposure of about 0.4 rads, focused on the breast rather than on the entire chest.
"Thus, premenopausal women undergoing annual screening over a ten-year period are exposed to a total of at least 4 rads for each breast, at least 8 times greater radiation than FDA's "cancer risk" level," Dr. Epstein calculates, warning, "Such high radiation exposure approximates to that of Japanese women living approximately 1 mile away from the site of the Hiroshima atom bomb explosion."
This alarming information is not new, explains Dr. Epstein. In 1972, the prestigious National Academy of Sciences warned that the overall risks of breast cancer increase by 1% for every single rad exposure. This totals a 10% risk from 10 years annual premenopausal mammography.
This warning was emphasized in Dr. Epstein's 1978 book, The Politics of Cancer, which states, "Whatever you may be told, refuse routine mammograms, especially if you are pre-menopausal. The x-rays may increase your chances of getting cancer."
A 1993 Swedish study involving 42,000 women showed that those under the age of 55 who received regular premenopausal mammography experienced a 29 percent greater risk of dying from breast cancer.
Based on a detailed review of these and a wide range of other such studies, the late Dr. John Gofman, the leading international authority on medical radiation, published an analysis in his classic 1995 book, Preventing Breast Cancer. He stressed that medical radiation is probably the single most important cause of the modern breast cancer epidemic.
These warnings were further detailed in a 2001 article, with some 50 scientific references, "The Dangers and Unreliability of Mammography: Breast Self Examination As A Safe Effective and Practical Alternative," published in the prestigious International Journal of Health Services. This was co-authored by Dr. Epstein, by Dr. Rosalie Bertell, a leading international expert on the dangers of radiation, and by the late Barbara Seaman, founder and leader of the women's breast cancer movement.
An analysis of several 1993 studies showed that women who regularly performed monthly breast self-examination (BSE), particularly following training by qualified nurses, detected their cancers much earlier than those who failed to do so. That most breast cancers are first recognized by women themselves was even admitted by the American Cancer Society (ACS) as early as 1985, when the organization stated, "We must keep in mind that at least 90 percent of women who develop breast cancer discover the tumors themselves."
The International Journal of Health Services article further stressed that cancer risks from mammography are up to fourfold higher for the 2 percent of women who are silent carriers of a gene known as the A-T (ataxia-telangiectasia), and highly sensitive to the carcinogenic effects of radiation. This accounts for up to about 20 percent of all breast cancers diagnosed annually.
"This wide range of concerns on the still unrecognized dangers of routine premenopausal mammography are critical, especially in view of the current high incidence of breast cancer," Dr. Epstein warns. "Disturbingly, this has increased by about twenty percent since 1975 in spite of routine premenopausal mammography, and its multi-billion dollar insurance costs. Such funds should instead be directed to establishing BSE training clinics nationwide."
Five radiologists have served as presidents of the American Cancer Society, Dr. Epstein notes, warning, "In its every move, the ACS promotes the interests of the major manufacturers of mammography machines, particularly the latest digital machines. These are four times more expensive, but no more effective than the film machines."
Dr. Epstein observes that the mammography industry conducts "research" for the ACS and its grantees, serves on its advisory boards, and donates considerable funds. "In virtually all its actions, the ACS has been and remains strongly linked with the industry."
He quotes an ACS communications director who said in a 1999 article published by the Massachusetts Women's Community's journal Cancer, "Mammography today is a lucrative [and] highly competitive business."
Urging "a national boycott of the American Cancer Society," Dr. Epstein points out, "The prestigious Chronicle of Philanthropy, the nation's leading charity watchdog, has warned the obvious, the ACS 'is more interested in accumulating wealth than saving lives.'"
