Millions of women undergo them annually, but few are even remotely aware of just how many dangers they are exposing themselves to in the name of prevention, not the least of which are misdiagnosis, overdiagnosis and the promotion of breast cancer itself.
A concerning study published in the Annals of Family Medicine titled, Long-term psychosocial consequences of false-positive screening mammography, brings to the forefront a major underreported harm of breast screening programs: the very real and lasting trauma associated with a false-positive diagnosis of breast cancer.
The study found that women with false-positive diagnoses of breast cancer, even three years after being declared free of cancer, "consistently reported greater negative psychosocial consequences compared with women who had normal findings in all 12 psychosocial outcomes."
Sense of dejection
Negative impact on behavior
Negative impact on sleep
Degree of breast self-examination
Negative impact on sexuality
Feeling of attractiveness
Ability to keep 'mind off things'
Worries about breast cancer
What is even more concerning is that "[S]ix months after final diagnosis, women with false-positive findings reported changes in existential values and inner calmness as great as those reported by women with a diagnosis of breast cancer."
In other words, even after being "cleared of cancer," the measurable adverse psychospiritual effects of the trauma of diagnosis were equivalent to actually having breast cancer.
Given that the cumulative probability of false-positive recall or biopsy recommendation after 10 years of screening mammography is at least 50%, this is an issue that will affect the health of millions of women undergoing routine breast screening.
The Curse of False Diagnosis and 'Bone-Pointing'
Also, we must be cognizant of the fact that these observed 'psychosocial' and 'existential' adverse effects don't just cause some vaguely defined 'mental anguish,' but translate into objectively quantifiable physiological consequences of a dire nature.
For instance, last year, a groundbreaking study was published in the New England Journal of Medicine showing that, based on data on more than 6 million Swedes aged 30 and older, the risk of suicide was found to be up to 16 times higher and the risk of heart-related death up to 26.9 times higher during the first week following a positive versus a negative cancer diagnosis.
This was the first study of its kind to confirm that the trauma of diagnosis can result in, as the etymology of the Greek word trauma reveals, a "physical wound." In the same way as Aborigonal cultures had a 'ritual executioner' or 'bone pointer' known as a Kurdaitcha who by pointing a bone at a victim with the intention of cursing him to death, resulting in the actual self-willed death of the accursed, so too does the modern ritual of medicine reenact ancient belief systems and power differentials, with the modern physician, whether he likes it or not, a 'priest of the body.'; we must only look to the well-known dialectic of the placebo and nocebo effects to see these powerful, "irrational" processes still operative.
Millions Harmed by Breast Screening Despite Assurances to the Contrary
Research of this kind clearly indicates that the conventional screening process carries health risks, both to body and mind, which may outstrip the very dangers the medical surveillance believes itself responsible for, and effective at, mitigating. For instance, according to a groundbreaking study published last November in New England Journal of Medicine, 1.3 million US women were overdiagnosed and overtreated over the past 30 years. These are the 'false positives' that were never caught, resulting in the unnecessary irradiation, chemotherapy poisoning and surgery of approximately 43,000 women each year. Now, when you add to this dismal statistic the millions of 'false positives' that while being caught nevertheless resulted in producing traumas within those women, breast screening begins to look like a veritable nightmare of iatrogenesis.
And this does not even account for the radiobiological dangers of the x-ray mammography screening process itself, which may be causing an epidemic of mostly unackowledged radiation-induced breast cancers in exposed populations.
For instance, in 2006, a paper published in the British Journal of Radiobiology, titled "Enhanced biological effectiveness of low energy X-rays and implications for the UK breast screening programme," revealed the type of radiation used in x-ray-based breast screenings is much more carcinogenic than previously believed:
"Recent radiobiological studies have provided compelling evidence that the low energy X-rays as used in mammography are approximately four times - but possibly as much as six times - more effective in causing mutational damage than higher energy X-rays. Since current radiation risk estimates are based on the effects of high energy gamma radiation, this implies that the risks of radiation-induced breast cancers for mammography X-rays are underestimated by the same factor.
