BBC: HRT 'doubles breast cancer risk'
Taking certain types of hormone replacement therapy (HRT) can double the risk of developing breast cancer, says a study of more than a million women.

This is an irresponsible, scaremongering headline (whether they use inverted commas or not). Saying that a risk is doubled doesn't say anything about how much risk there actually is. If I buy two lottery tickets instead of one tomorrow, I double my chances of winning the jackpot, but the odds against it are still around eight-million to one.
