Scientists have discovered that drinking just three cups of coffee a day can make women's breasts shrink.
Nearly 300 women were surveyed about their bust measurements and how many cups of coffee they drank in an average day.
According to researchers, three cups a day was enough to start making breasts shrink, with the effects increasing for every cup drunk.
They said there was a clear link between drinking coffee and smaller breasts as around half of all women possess a gene that has been shown to link breast size to coffee intake.
'Drinking coffee can have a major effect on breast size,' said Helena Jernstroem, a lecturer in experimental oncology at Lund University in Sweden.
'Coffee-drinking women do not have to worry their breasts will shrink to nothing overnight.
They will get smaller, but the breasts aren't just going to disappear.'
'However, anyone who thinks they can tell which women are coffee drinkers just from their bra measurements will be disappointed.'
'The problem is that there are two measures for a bra, the cup size and the girth, so you wouldn't be able to tell.'
It's not all bad news for women however as the researchers also found that regular hits of caffeine can help to cut the risk of developing breast cancer.
Scientists said that the effect of coffee is related to its impact on estrogens - the female sex hormones.
Some substances in coffee can change a woman's metabolism so she acquires a better configuration of various estrogens, therefore lowering the potential risk.
But women with bigger breasts that contain more mammary glands are at a higher risk, the scientists added.
