Today's CNN a study has found a Correlation between coffee consumption and low liver cancer rates.
Please note, that this study cannot prove a causal relationship. Even with the information we have on rodents, actual experiments need to be conducted before people who are worried about liver cancer should start pounding the Starbucks.
In a study like this one, which is merely observing people and reporting on results there are very high incidents of lurking variables. Maybe individuals who tend to drink more coffee, drink less alchohol (a risk factor for liver cancer). There are all kinds of possible explainations.
The Bad Headline Award goes to:
The India Times with "A coffee a day can keep cancer at bay."
Not only misleading, but rhyming as well
