Comments on: How much do we really need mammograms? http://www.kevinmd.com/blog/2009/04/how-much-do-we-really-need-mammograms.html Tue, 14 Feb 2012 19:56:00 +0000 hourly 1 By: Diorahttp://www.kevinmd.com/blog/2009/04/how-much-do-we-really-need-mammograms.html#comment-90776 Diora Thu, 09 Apr 2009 16:17:00 +0000 http://clients.emmense.com/kevinmd/2009/04/how-much-do-we-really-need-mammograms.html#comment-90776 Jen, this "disruption" can have consequences that go beyond inconvenience. Surgery, for example, has risks and while these risks may be small, when you consider a large numbers of women affected, they will add up. Overtreatment may damage someone's health or quality of life forever. Is one woman's life saved worth an unnecessary mastectomy (and associated risks of surgery)? What about 5 unnecessary mastectomies? What about unnecessary radiation treatment that increases one's risk for heart disease and even sarcoma later in life? Yes, risks may be small, but so is the probability of an individual benefiting. Even anxiety from false positives that can be accompanied by a raise in blood pressure may be harmful to someone's health. Again, you may say that this is a small price to pay for a decreased risk of dying from breast cancer, but when you consider that your risk of having at least one false positive within 10 years of screening is almost 50%, the number of women affected might be quite large.<br/><br/>Also, keep in mind that no study showed the decrease of all cause mortality from screening, only breast cancer mortality. So if, for example, more screened women die from heart disease, it is impossible to determine. <br/><br/>Another problem with emotional "my life was saved" stories is that in any particular case there is no real certainty that a particular life was indeed saved. In some cases the early cancer represented over-diagnosis so a woman may have lived a long life without ever knowing she had cancer. In other cases, the cancer could have still been curable if detected later. Yet in another case, the cancer can still come back and kill you anyway. It's only in a subset of these "my life was saved" stories where one's life was really saved.<br/><br/>I imagine that many women would indeed prefer mammograms, and it is fine. But I think that some women may refuse, and I believe their choice has to be respected. Currently there is this pervasive mentality that women have to be persuaded, dragged, shamed into having mammograms because it is "a responsible thing to do". I think this has to stop. We are thinking and intelligent human beings who are capable of making our decision, but to do so we need accurate information. Jen, this “disruption” can have consequences that go beyond inconvenience. Surgery, for example, has risks and while these risks may be small, when you consider a large numbers of women affected, they will add up. Overtreatment may damage someone’s health or quality of life forever. Is one woman’s life saved worth an unnecessary mastectomy (and associated risks of surgery)?

I do agree, though, that we need to make time for these types of conversations as well as the emotional stories of the lives saved. Because if our technology today isn’t good enough – the public needs to know so we can do something about it.

IMO – in this case, a flawed system is better than nothing. But we can’t hide behind it forever.

But many also see screening as a fundamental enabler in the establishment of high performance breast cancer clinics - so there is much more to it.

I'm at the point now where I avoid preventative tests because they are more headache than they are worth.
