(US News) 26 June 2008:

No, skin cancer isn’t one of those things you can get from sex: well, not unless you’re doing it outside a lot without sunscreren. However, there are major differences in the way that men and women suffer from the disease.

Men both get more cases of the various types of skin cancer and also are more likely to die of it if they get it. There is some evidence that male skin is simply more likely to become cancerous, but the major reasons seem to be twofold. The first is that men work outside more and thus gain more exposure, the second that they use much less sunscreen than women.

Another way of putting that last is that women simply pay more attention to the state of their skin overall: although might that change with the rise of metrosexuality?
