This is for a given value of \”doesn\’t work\” of course.
For the study, published in the British Medical Journal, falls in breast cancer death rates were compared in three pairs of similar territories: Northern Ireland to the Republic of Ireland; Sweden to Norway; and The Netherlands to Flanders in Belgium.
In the first of each pair screening was introduced 10 to 15 years earlier than in the second.
However, they found little difference between the pairs in breast cancer mortality rate falls from 1989 to 2006.
The percentage drops were as follows: Northern Ireland 29, Republic of Ireland 26; Sweden 16, Norway 24; Netherlands 25, Flanders 25.
The similarities \”suggest that screening did not play a direct part in the reductions in breast cancer mortality\”, they concluded.
A nice little natural experiment they\’ve exploited there too.
Quite what this means in terms of policy though…….I have a feeling there\’s rather too much investde in the whole idea of mass screening for anyone, in political reality, to be able to stop it.
