@Sqad, Aye, I have read Gotzsches review for the Cochrane Collaboration before, and it did rather put the cat amongst the pidgeons when it came out :)
The latest report I saw (Duffy et al) was aware of Gotzsches work, and pointed out that he had focused on a 10- year interval, rather than the longer 20 year time period, which may have scewed the findings. somewhat.
Its all about balance of benefits and harms, and it is certainly true that the programme is not entirely beneficial, in that there will be a cohort of women who are over-diagnosed and receive unnecessary treatments - This is not something that is widely understood, and it is obviously important from an informed consent perspective that women understand the risks.
The work of Duffy et al looks at that longer time frame and offers a different benefits ratio in consequence...

Fortunately for me, this all remains a hypothetical risk. Were I a woman in that age range though, I would opt for the screening programme....
