Are you a woman, and a coffee consumer? Then this is not good news for you or maybe it is. A new Swedish study suggests that drinking a lot of coffee reduces the size of many women’s breasts. The study leader, Helena Jernstrom an oncologist at Lund University in southern Sweden said that the effect is the result of a gene that about half of women possess. “Drinking coffee can have a major effect on breast size,” she said.

The goal that Jernstorm wanted to achieve, is to examine the relationship between drinking coffee and breast size. He study have shown that large-breasted women are more likely to be diagnosed with breast cancer, while downing at least three cups of coffee a day reduces cancer risk.
