Drinking coffee too often decreases the size of your breasts

A recent study done on 269 women concluded that 3 cups of coffee a day can actually reduce the size of breasts.

The study was published in the British Journal of Cancer, hardly a sensationalist publication – and the actual study was not really all that sensational. Titled “Coffee intake and CYP1A2*1F genotype predict breast volume in young women: implications for breast cancer,” the Swedish researchers had a group of 269 women from families with a high risk of breast cancer fill out a questionnaire about their use of coffee. They also measured the breast volumes of each of the women and tested samples of their blood for specific hormones and genes.

They were looking for a relationship between coffee consumption, breast size, and breast cancer risk – and they had a specific reason for doing so. Previous research had shown a correlation between coffee drinking and a reduced risk of breast cancer. Other research had found a correlation between breast size and reduced risk of breast cancer. The Swedish group was looking to see if there was a direct correlation between breast size and coffee consumption. They did find one – but the findings are far more complicated than the simple headlines and news stories made them appear.
