Reports this week from British Medical Journal with more evidence from the USA on Mammography results!

Screening Mammography resulted in over diagnosis in 1.3 million women in the past 30 years. The study in the New England journal of medicine estimates that more than 70,000 women in the US were over diagnosed in 2008 representing almost a third of all cases in breast cancer diagnosed in women aged 40 or over. Although the rate of death from cancer fell considerably this was largely due to the result of better treatment, not screening.

This study further raises the question about screening.
