Breast screening is a subject that tends to stir up strong emotions both for and against. At the risk of upsetting people I feel I must tell you that some researchers really have their doubts about the efficacy of breast screening.
"However a new study, from Denmark, now casts doubt on the value of breast screening programs. In 2005, a study suggested that breast screening had reduced breast cancer deaths in Copenhagen by as much as 25%. But the study was thought to have some problems and the conclusions were in doubt. Therefore, scientists at the Nordic Cochrane Center and elsewhere decided to take another look and carried out a more comprehensive analysis of breast screening data."
The study from Denmark reports that while breast cancer mortality dropped by 1 percent in areas where screening was performed, it dropped by 2 percent in the areas without screening. In younger women -- too young to need breast screening -- mortality dropped 5 percent in screening areas, and 6 percent in non-screening areas. In older women there was no difference for the two groups.
