New Study: 1/3 of Tumors Found in Mammograms are Harmless

mammogramimage 255x159 New Study: 1/3 of Tumors Found in Mammograms are HarmlessResearchers of a new study published in the New England Journal of Medicine claim that the push for breast cancer exams in the past 30 years has caused 1.3 million American women to be overdiagnosed. Dr. H. Gilbert Welch of Dartmouth College’s Geisel School of Medicine argues that the decrease in breast cancer mortality rates is owed more to improved treatment than screenings, which detect even small, possibly benign and temporary abnormalities that resolve themselves.
Many breast imaging specialists, like Dr. Danial B. Kopans of Massachusetts General Hospital in Boson, railed against the findings, calling it “malicious nonsense” designed to deny women access to screening to reduce healthcare costs.

Early Screenings and False Positives

While the study authors agree that screening has detected early-stage cancers, it must also by this reasoning reduce the incidence of late-stage cancers (because the tumors would have been removed sooner). But they haven’t, the authors say.
After analyzing data between 1976 and 2008 from the National Cancer Institute and the Centers for Disease Control and Prevention, they found that early-stage cancers doubled (per 100,000 women) from 112 to 234, but late-stage cancers fell by only 8 cases, from 102 to 94.
“We hear the word ‘cancer,’” says Welch, “and we all assume the definition that’s in my medical dictionary—it’s a tumor that, left untreated, will inexorably grow and cause death. But now, as we look for really early forms of the disease, we realized the pathologic definition of cancer includes abnormalities that may come and go.” (Welch clarified that although he is not telling women to resist screenings, they should be conscious of the technology’s limitations.)
Stamatia Destounis, a Rochester breast imager, was dubious on the matter. “There is no way for us to know which early-stage breast cancer would not progress and which one would…. How would we tell a patient, ‘Chances are this is early and it’s probably not going to progress for a long time, if ever’?”

Dangerously High Screening Rates

This isn’t the first time breast imaging has come under attack; in 2009, the US Preventative Services Task Force concluded that current levels of testing put women under unnecessary financial and emotional duress. They also noted that false positives and unhealthy exposure to radiation were a growing concern. Several Harvard Medical School academics also echo Welch’s opinion that screening rates are unnecessarily high, and even mainstream health officials like Danish scientist Peter Gotzshe admit that screening isn’t always all it’s cracked up to be.
It can also be argued that the very organizations advocating aggressive screenings—like Susan G. Komen—are engaged in fraud for using misleading statistics to promote screening, offering free screenings that may or may not raise the risk of future development of cancer, and by skirting scientifically relevant issues to breast cancer, like its link to BPA.
Unfortunately women are driven by massive amounts of fear of breast cancer, so much so that some individuals are actually cutting off their breasts in order to be risk-free.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to believe
that I was supporting praying to change the weather. So, when I select
articles which are in favor of drugs, anti-Semitic, anti-Jewish, racist,
revisionist, or inciting hatred against any group or religion, or any
other stupid article, it does not mean that I support them. It just
means that it is important for all human beings to know about them.
Common sense, which is usually very good among our readers, is good
enough to understand that. When, like in the recent articles on drug
decriminalization, it is necessary to make it clearer, I add a comment,
which in this case was very clear: I support decriminalizing all drugs,
as it is stupid to throw depressed and sad people (as only depressed and
sad people use drugs) in prison and ruin their life with a criminal
record. That does not mean that there is any change to the Message which
says clearly that we must not use any drug except for medical purposes.
The same applies to the freedom of expression which must be absolute.
That does not mean again of course that I agree with anti-Jews,
anti-Semites, racists of any kind or anti-Raelians. But by knowing your
enemies or the enemies of your values, you are better equipped to fight
them. With love and respect of course, and with the wonderful sentence
of the French philosopher Voltaire in mind: "I disapprove of what you
say, but I will defend to the death your right to say it".

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
