Does mammogram row signal time for policy shift?Does mammogram row signal time for policy shift?Almost any woman who had a cancerous tumor detected in her breast during a regular screening appointment would probably think the scan -- and subsequent surgery#x, radiotherapy or chemotherapy treatment to remove the cancer -- saved her life.But that is not always true and an increasingly heated international debate is raging about whether women are getting the right information on the merits,Stone Bladeand risks, of mammograms.The fear is that over-diagnosis -- when screening picks up tumors that would never have presented a problem -- may mean many women are undergoing unnecessary radical treatment, suffering the physical and psychological impact of a breast cancer diagnosis that would otherwise not have come up.While some scientists are locked in battle, slinging accusations at each other of misleading data and conflicts of interest, others say the row itself is a signal that it's time for a new and more refined approach to breast cancer screening.
"What really bothers me...is the poor women who are the subjects of this debate, who must be utterly confused and not know what the hell is going on or what to do," Michael Baum, the doctor who introduced Britain's first breast screening program more than 20 years ago, told Reuters."To carry on regardless is no longer acceptable.#x I'm trying to find a way out of this mess."ROW ERUPTSLow level argument over the merits of mammograms has bubbled for some years,Stone Bladebut a political storm blew up in the United States last year when public health officials questioned whether screening for women in their 40s actually save lives and proposed upping the regular screening age to 50.Now, in Europe, two recent scientific studies have brought the issue to a head, pitting convinced breast cancer screening supporters against those who say the numbers just don't add up.A team of Danish scientists published a study showing that breast cancer screening programs of the type run by health services in Europe, the United States and other rich nations do nothing to reduce death rates from the disease.A week later, a British team published a study showing a "substantial and significant reduction in breast cancer deaths" due to screening.The lead researchers on each paper,Carbon fiber hood, Stephen Duffy of Queen Mary, University of London,Stone Bladewho led the British study, and Peter Gotzsche of the Nordic Cochrane Center, who led the Danish team,#x told Reuters they suspected the other of having long-held biases on breast cancer screening that skewed their work.相关的主题文章：
