A new Open Access paper in the bmj compares breast cancer incidence and mortality up to 25 years in women aged 40-59 who did or did not undergo mammography screening. It concludes: ‘Annual mammography in women aged 40-59 does not reduce mortality from breast cancer beyond that of physical examination or usual care when adjuvant therapy for breast cancer is freely available’ and also ‘the data suggest that the value of mammography screening should be reassessed’.

The first (negative) rapid response is likely to draw some interesting observations.
Also, because the news is hitting the headlines worldwide (http://www.nytimes.com/2014/02/12/health/study-adds-new-doubts-about-value-of-mammograms.html) and is in the Uruguayan press this should greatly help Ana Rosengurtt`s brave campaign against mandatory mammography screening there.
