It’s logical, isn’t it? There is a nasty cancer – cancer of the breast; if we get it early and cut it out, obviously women with the problem will live longer. This has been the predominant belief for the past 30 years or so. However, what is the evidence and how has the evidence changed? Breast cancer screening, when introduced, was based on the belief ¹ that it goes without discussion that catching a cancer early would improve things. Whilst it was considered early on that there may be a down side, it is only very recently that these have become clear. The latest information gained for several different screening programmes confirms that the screening programme has actually caused many women to have unnecessary surgery. This was published in the Lancet and was attended by a lot of publicity. There is also an excellent NHS Cancer review looking at this paper ² .
