"In order to save one life from cervical cancer, the research found, 1000 women would need to be screened for 35 years. Worse, the researchers suggested that testing might do "more harm than good": women born after 1960, they found, have a 40 per cent chance of having a smear test labelled abnormal at some point in their lives"
a) 35 years is the standard time for screening in UK., from 25 to about 60. So they are saving one in one thousand women who follow the normal schedule I've run their lifetime. Sounds a bit different put that way, doesn't it?
b) when they say 'labelled abnormal' what did they mean? All CIN? If so, what proportion of those were CIN1 and had no intervention other than a time in enhanced recall?
There seems to be a fair amount of confusion about what the test results can mean. Perhaps more education on this, and how CIN1 does not need treatment, is a step that could usefully be taken. I think it's a good thing in itself to have more and clearer information readily available for medical matters and NHS protocols.
