Breast cancer league table, out today, suggests (to some of us) an epicentre of XMRV infection and genetic vulnerability to XMRV: http://www.dailymail.co.uk/health/a...ate-11th-highest-world.html?ito=feeds-newsxml 1. Belgium 2. Denmark 3. France 4. Netherlands 5. Israel 6. Iceland 7. Ireland 8. Uruguay 9. Switzerland 10. New Zealand 11. UK The top 4 are particularly suggestive, lying so close together as they do; looking at that from an epidemiological point of view might just be a clue as to either the origin of genetic vulnerability to XMRV or ground zero of XMRV in Europe. Note that Belgium, in particular, is way out in front. I wouldn't disagree with the factors mentioned in the article as partial explanations for the distribution, but of course as usual it's only the soft factors, lifestyle factors etc that are advanced as explanations - we have to add genetic factors and XMRV infection to that story. Very few posts on the discussion thread so far, and this will be across all papers today (GoogleNews search on 'breast cancer' stories today should find all the other articles). It's a good opportunity to add comments explaining XMRV and the breast cancer connection. Some background info, and references regarding the tentative links made between XMRV and breast cancer, would be required. First reference to breast cancer was from John Coffin, Oct 2009 CFSAC - thought at the time to be a slip of the tongue, meaning to say prostate cancer; subsequently when the suggestion of breast cancer/XMRV connection was made public we realised that this slip of the tongue implies that this connection has been known behind the scenes for nearly 18 months now. I think stories like this are a good opportunity to spread the word about XMRV to a wider audience.
