Mammograms!
Thank you to Dr Tim O'Shea for the following very important information on the practice of mammography:
“This is one topic where the line between advertising and scientific proof has become very blurred. As far back as 1976, the American Cancer Society itself and its government colleague the National Cancer Institute terminated the routine use of mammography for women under the age of 50 because of its “detrimental” (carcinogenic) effects. More recently, a large study done in Canada found that women who had routine mammograms before the age of 50 also had increased death rates from breast cancer by 36%. Lorraine Day notes the same findings in her video presentation “Cancer Doesn’t Scare Me Any More.” The reader is directed to these sources and should perhaps consider the opinion of other sources than those selling the procedure, before making a decision.
John McDougall MD has made a thorough review of pertinent literature on mammograms. He points out that the $5-13 billion per year generated by mammograms controls the information that women get. Fear and incomplete data are the tools commonly used to persuade women to get routine mammograms. What is clear is that mammography cannot prevent breast cancer or even the spread of breast cancer. By the time a tumor is large enough to be detected by mammography, it has been there as long as 12 years! It is therefore ridiculous to advertise mammography as “early detection.” (McDougall p 114)
The other unsupportable illusion is that mammograms prevent breast cancer, which they don’t. On the contrary, the painful compression of breast tissue during the procedure itself can increase the possibility of metastasis by as much as 80%! Dr. McDougall notes that a between 10 and 17% of the time, breast cancer is a self-limiting non-life-threatening type called ductal carcinoma in situ. This harmless cancer can be made active by the compressive force of routine mammography. (McDougall, p105)
Most extensive studies show no increased survival rate from routine screening mammograms. After reviewing all available literature in the world on the subject, noted researchers Drs. Wright and Mueller of the University of British Columbia recommended the withdrawal of public funding for mammography screening, because the “benefit achieved is marginal, and the harm caused is substantial.” (Lancet, 1 Jul 1995) The harm they’re referring to includes the constant worrying and emotional distress, as well as the tendency for unnecessary procedures and testing to be done based on results which have a false positive rate as high as 50%.” (New York Times, 14 Dec 1997)
