Uh, the new mammogram guidelines only apply to low-risk women who don't have any family history or high risk factors (such as smoking). Canada's been on a two-year mammogram cycle for women from ages 60-69 forever, as far as I know, and we're not dropping like flies up here.

Basically, the calculus went as follows -- they currently have to screen 1904 women to save one life, and a significant number of those 1904 women will wind up overdiagnosed and/or overtreated*, and Canada and half of Europe uses a similar schedule with very little ill effect, so the risk-benefit ratio came out somewhat in favour of recommending less frequent testing.

Citation, with tons and tons of linkies in the article itself.

This is not ZOMG PANIC TEH GUVERMINT HATES TEH WIMMINS (this time). And it's certainly not worth all this panic, FUD, and fearmongering.

* Overdiagnosis means that they found something that looked like it could be a tumour, but wasn't, and thereby subjected the woman in question to a cancer scare, a couple in-retrospect-unnecessary biopsies, and all that stuff, or they found one of those tumours that spontaneously disappears after a while, or they found the kind of tumour that's so non-aggressive the woman in question will die before the cancer kills her -- but once you find something suspicious, you have to treat it, hence also "overtreatment."

They are using the best science available to make a blanket recommendation to the entire general public. As you pointed out this test carries with it a huge amount of anxiety which is not helped by false positives and unnecessary biopsies. We are free to do whatever we want to do individually however and us men can have the finger every six months if that's what we want. (I won't!)

It seems reasonable for insurance companies to follow established scientific guidelines in determining what they will pay for. Patients don't have the right to ask someone else to pay for unncessary procedures just because they have a high level of anxiety.

To be fair, I never said this was a case of the government (or anyone else) hating women. That's not my point.

The idea of this only applying to low-risk women gets lost. The idea that people who might not have a full view of their family history (adopted folks, people who have a limited contact with family, people who don't sit around and talk about cancer at Thanksgiving) creates and issue here, but that gets lost as well.

The point is that if something is more of a requirement, we tend to do it more. When things are "optional" we tend to dodge them if they are unpleasant. Adding to the sense that you put the weight of a governmental/medical study behind anything, boil it down into a simple newspaper article (the vast sums of people are probably not rolling through a transcript of NPR) and you've got this:

"You don't need one of these when you're 40. The paper says so."

But Doc, how are Canada and Europe any different? They adopt kids there, they have low and high risks, too. If they're not dropping like flies, from this or any other cancer, the benefits you imagine are just that -- imaginary. This sort of measurement is a good thing; it's what some of us use as a rhetorical club on the jerks who don't think universal health care is a moral issue -- we can point out that it is also cheaper and works better, everywhere it has been tried.

When I'm teaching Evidence Based Medicine classes, one of my talking points is that they take mega-studies of a large number of people.

Using those studies, I can tell you what percentage of the people will have certain things happen to them. But I can't tell you about the individual patient.

Then the TV reports a group report(albeit with good credentials)and everyone freaks out and thinks that is the thing they do immediately - not understanding that it needs more review.

Well, one point: plenty of insurance companies do not now cover the entire cost of a mammogram, which keeps a lot of women from having them every year. I was in that category when I had to buy my own insurance--the insurance only covered a portion of the cost, so I got hit with $300 when I got the mammogram. So insurance companies already ration that sort of care--but I agree--they will now balk at paying for a mammogram for women under 50, citing this study as support. But that is more a case of the insurance companies hating on people than the government doing so.

Cancer scares the crap out of me. Certainly enough to get me to go get a mammogram now that my doc has told me I should start getting them.

But not enough that I won't procrastinate like crazy. 5 weeks and counting...

BTW, Doc, my dad works as a standardized patient (meaning he is a guinea pig for student docs to try out their mad skilz on). One of his regular gigs is as a prostate examinee. He likes to tell everyone (much to my embarassment and dismay) that he has the best examined prostate on the planet.

That should be near the top of everyone's list of "Things You Never Want To Hear Your Parents Talk About."

i am going with what ibang said. so i can wait til 60 or dead.

Hang on.

A change in recommendations made to most people

from

one based in a fear of missing something

TOWARDS

an equally effective and less expensive endpoint

and this is bad policy?
