Around half of all women possess a gene shown to link breast size to coffee intake.
“Drinking coffee can have a major effect on breast size,” said Helena Jernström, a lecturer in experimental oncology at Lund University.
But while a regular brew appears to have a somewhat deflationary aspect, there is also one very positive effect in that coffee reduces the risk of breast cancer.
Woman with an average weight but big breasts and a high number of mammary glands run an above average risk of developing breast cancer.
Previous studies have shown that women can reduce this risk by drinking at least three cups of coffee a day.
Jernström wanted to know if there was a further correlation: If drinking coffee and breast size were both connected to the risk of developing breast cancer, could there also be a link between coffee and cup size?
Studies carried out on almost 270 women showed that there was indeed a clear connection between coffee and smaller breasts. The results of Jernström’s findings have been published in the British Journal of Cancer.
