Abstract
So far, we have been considering numerous factors that are relevant to answer the main question of this book: what screening programmes are morally justified? As we have seen, this hinges on so many factors that it may be hard to see the full picture. In this chapter, we would like to bring these factors together in order to assess different screening programmes that are implemented or suggested. We will do this by considering four contested (types of) screening programmes. Some of these are already up and running, while others are in development or, at least, seriously contemplated for the future. The number of screening programs up and running in the world are legio. They become even more numerous if we include suggested ones. A selection has to be made in order to make the discussion manageable. But why have we selected these ones? Primarily because they are of current interest, controversial, and telling regarding the general debate on which screening is defensible. Non-invasive prenatal diagnosis (Section 5.1) is the next frontier of prenatal diagnosis. Screening for fragile X (Section 5.2) is, similarly, an instance of the next frontier for neonatal screening, since it is an instance of screening for a disorder for which there are few medical benefits of screening (which is a clear difference from PKU-screening). In this regard, it is a case that illuminates the wider question of which benefits that are relevant for assessing (neonatal) screening programs.

Notes
- 1.
The careful reader will note that we have represented cases of prenatal, neonatal, and adult screening, but not adolescent screening. The reason is that adolescent screening programmes are rarely suggested (although there are exceptions, e.g. ATD-screening, see Section 3.3.2) and even more rarely implemented. One notable exception is HPV (human papillomavirus). However, then it is seldom screening in isolation that is discussed but screening in conjunction with vaccination, which brings a host of ethical problems of their own (Dawson, 2007). For an excellent discussion of these problems, see Malmqvist et al. (2010).
- 2.
To go on adding similar cases of adult screening programmes, e.g. colon cancer screening, would only lead to tiresome repetition. We trust that interested readers would be able to extrapolate from the cases presented.

While, e.g., the immediately visible autism-type symptoms of fragile X may be noticed rather soon, it is of both psychosocial and therapeutic importance to know whether the symptoms are caused by fragile X or not. For instance, while the classic sign of lack of eye contact, physical touch and verbal interaction may, in the general autism case, often be due to a straightforward inability of the child (possible to gradually repair through special training and adapted surroundings), in the specific case of fragile X, it rather seems to be due to these basic social and communicative behaviours causing discomfort, therefore being rationally avoided by the child. See, e.g., Dew-Hughes (2003); and Jenssen Hagerman and Hagerman (2002).

A pioneer in this regard has been Czech, Dublin-based expert in oncology and preventive medicine, Petr Skrabanek, who published a long series of critical appraisals of mammography screening in The Lancet and other leading medical journals, as well as instigating general discussions of the ethics of medical prevention, starting as early as 1985 (Skrabanek, 1985). See also Skrabanek (2000).

Partly to avoid this, the Cochrane Collaboration has developed an alternative information leaflet to women invited to mammography screening, in which all figures are represented in terms of ratios rather than relative percentage. See http://www.cochrane.dk/screening/mammography-leaflet.pdf.

Again, the are great differences between screening in the US and in Europe seems to be partly due to the differences in health care systems. In the US, screening is driven by the commercial health sector, which, at least partly, likely explains why it was introduced without being officially evaluated first (however, also in the case of the US, PSA investigations amount to screening in the sense defined in Section 1.3). Here different socio-economic structures explain why screening looks like it does, just like in the case of neonatal screening (see Section 3.1.2.3).

For instance, the Quebec study had very low compliance in the screening group, the Norrköping study reported widely in the media about the study (increasing the likelihood of testing among the control group) and neither study compared outcomes with possible confounders, such as socio-demographic data.
