Awakening to the Consequences of Breast Cancer Over-Screening & Over-Diagnosis: Prominent Study

This blog entry contains personal editorial opinions and is not intended as medical advice.  Readers are encouraged to do their own homework and seek advice from sources they deem appropriate.

How many of you know 3 women who have been diagnosed at some point with breast cancer?  Perhaps one of these women is you.

Do you know anyone diagnosed with early stage breast cancer who suffered or even died from complications resulting from treatment? 

What if almost 1 out of the 3 women you know may have been the subject of inappropriately aggressive screening, never requiring any diagnosis or treatment at all?

More troubling yet, what if the screening itself did little to prevent the number of women overall dying from breast cancer?

It's Thanksgiving, and although I really didn't expect to be blogging about breast cancer tonight, I couldn't help but be thankful for a stunning article on breast cancer featured on the front page of my local newspaper, revealing concrete facts about a tragic situation many awakening women like me have suspected for quite some time.

As stated in the Oregonian today: "In the last 30 years, more than a million women have been diagnosed with breast cancer when they didn't have it or had a low-level, non-threatening form, according to a new study" from a respected oncologist and medical school professor.

The comprehensive, long-term study of U.S. women also concludes that early screening by mammograms has had only "marginal" impacts on women dying from breast cancer, precisely what widespread early screenings are actually supposed to prevent.

Here is a direct quote from the study conclusions in The New England Journal of Medicine itself:

"Despite substantial increases in the number of cases of early-stage breast cancer detected, screening mammography has only marginally reduced the rate at which women present with advanced cancer. Although it is not certain which women have been affected, the imbalance suggests that there is substantial overdiagnosis, accounting for nearly a third of all newly diagnosed breast cancers, and that screening is having, at best, only a small effect on the rate of death from breast cancer."

An earlier 2009 study in the British Journal of Medicine had similar conclusions about overly aggressive screening and diagnosis, its confirmation in my opinion a beautiful demonstration of the scientific method at work.  Also in 2009, what one of the panelists later said was "aimed at reducing the potential harm from overscreening", the independent U.S. Preventive Services Task Force panel appointed by the Department of Health and Human Services questioned the widespread use of mammograms before the age of 50.

Yet still, many refuse to listen, refuse to even reflect upon the possibility that women are being over-screeened, and it is absolutely astonishing how few mainstream news organizations are choosing to highlight this latest study, one that significantly impacts the choices and lives of women worldwide.  Women continue to be confused by conflicting recommendations from enthusiastic cancer charities supporting mammography, as well as doctors from the American Medical Association, whose careers depend upon treating these cancers.

As much as a growing number of women understandably celebrate being breast cancer "survivors", sadly the label itself has been rendered irrelevant in almost a third of these cases.  What almost 1 in 3 of these women actually "survived" was the treatment of breast cancer, based on an overly aggressive diagnosis they actually didn't need to receive at all.  How could their lives have been impacted if they could go back to that time before they knew, before their families knew, before their lives were turned upside down?  And what about those woman with early diagnoses who died from complications from the treatment?  The latest study says nothing about their untold numbers.

Nothing can be done now about the past, but what we can do is let future women know they actually have choices based on what more and more studies are revealing, despite the controversy.  These conclusions may be a bitter pill for many brave "survivors" to swallow, but what it really contains is hope, hope that will significantly reduce needless suffering for many women in the hands of an industry with profits fueled more by fear than facts.

As much as we would like to be handed clear, safe, unambiguous medical advice regarding the decisions we are called to make, unfortunately it's not that simple.

The studies show there are very real risks to over-screening, just as there are risks to being one of those unscreened women unfortunate enough to have a form of cancer that actually needs to be treated.  But the latest statistics tell us the screening itself does little to help, no matter what enthusiastic, well-meaning mammogram cheerleaders have told us in the past. And it's not necessarily safer to go for screening "just in case", a common misconception, particularly if you are one of those women exposed to the risks of over-treatment as a result.

And though it is a shocking thing to ponder, we must also be aware that the cancer screening and treatment industry brings in billions of dollars every year, and as much as we would like to believe that the motivations of the industry are lily white and pure, free from any profit motive whatsoever, the more wise and realistic among us will begin to realize just how unlikely that scenario actually is. Note that some cancer survivors have even recently surfaced and criticized corporate profit motivations behind wildly popular Pink Ribbon events - see the trailer for the 2012 documentary Pink Ribbons Inc. for that alternative point of view.

I took responsibility for my own choices long ago.  Due to being over-screened, over-radiated and over-stressed by diagnostic mammograms in the past (the ones you get when you are called back after a screening), I don't get mammograms anymore and haven't for several years.  I have encountered a number of other women quietly making the same choice despite the popular opinions of many of their well-meaning peers.  If I ever felt I needed something to be checked out, I would choose thermography and/or ultrasound instead.  I would choose alternative treatments too.

Few of us choose take a full body scan to go hunting around for other types of cancers, and I quite honestly have for years viewed mammography quite the same way. (And don't get me started about the choices I will some day be called to make about colonoscopy, a test that is NOT risk-free, a test I will some day consciously choose to skip.)  These are my choices as an empowered individual.  I see the logic and research behind my own choices as minimizing my overall risks, not the other way around. You are free to conclude and choose otherwise.

I personally have someone close to me who was diagnosed with breast cancer many years ago and chose not to do chemo for a rather advanced case that wasn't even seen in a mammogram at the time (albeit the technology was more limited back then).  She was aggressively warned (even bullied) by doctors who said she would die because of her courageous choice.  She survived many years and is still with us now, healthy and cancer-free, her life a testament to the choice doctors tried to take away.

I know someone else who spontaneously recovered from another form of late-stage cancer after being told by the doctors she had no choices left at all.   She too has been cancer-free for several years.

These are stories of survivors, but not the stories you usually hear.  These are stories of empowered, courageous women who granted themselves the power to Choose.  Often women are told that the "brave" thing is to do what the doctor says, often coached by other treatment survivors who have made that same choice, but no matter what a person chooses, the brave thing is to be empowered enough to make your own choice, to realize that you do indeed have a choice to do your own homework, no matter what your final decision happens to be.

I  know someone who almost died from optional chemo after being diagnosed with early stage breast cancer, thinking she was taking a cautious, conservative route for a rather minor diagnosis.  She was one of the healthiest, fittest women I knew at the time.  She made her choice, one she thought was the safest thing to do, yet within a very short time, it almost took her life.

Yes, of course there are women who have done everything they were told by the doctors and survived, women who credit the medical profession with their survival.  I do know women like that too, and some of them no doubt were indeed saved, particularly those diagnosed in later stages.  As for the others, how many of them needed to be screened, diagnosed and treated at all?  I will never know.  Nor will they.  And the latest study backs that up.

Not everyone survives alternative approaches.  But not everyone survives what the doctors and pharmaceutical companies tell you either.  Doctors are not gods, nor are they anywhere close to perfect.  Sometimes they give you good advice.  Sometimes they don't.  And often they make mistakes.  Therein resides the ambiguity and responsibility of personal choice.

It's time for the women who have had the courage to explore alternative choices to speak.  We can be the voices for the unknown number of silenced women who have suffered and died needlessly from over-screening and subsequent over-treatment complications, those unnecessarily taken from their families far too soon, women who actually had choices they may never have been led to contemplate at all.
