The article said that only uncircumcised men get cancer of the penis. The fact was presented as uncontroversial.
This worried me two ways.
I Googled and found pages denying the link that I had found so worryingly implausible.
I don't really know what to make of this. Well actually I think that I do. Apparently penis cancer is rarer than breast cancer which itself is too rare to worry about (I'm a man!) So I'll just forget all about it. (Except that it strikes me as another case of using a rare illness to scare people - since it is rare there will be a lack of solid information)
