Women with asymmetrical breasts are at greater risk of developing breast cancer, it has been claimed.
Scientists from the University of Liverpool have published a paper in Breast Cancer Research showing that breast asymmetry can be used as a "significant independent predictor" of breast cancer.
Diane Scutt, who led the research, claims that for every 100ml difference between women's breasts, the relative odds of breast cancer increased by 1.5.
"We found that breast asymmetry was greater in the healthy women who subsequently developed breast cancer than those who remained disease free," the report stated.
"Asymmetrical breasts could prove to be reliable indicators of future breast disease in women and this factor should be considered in a woman's risk profile."
One in nine women will develop breast cancer at some stage during their life, but developments in treatment and earlier detection have reduced fatalities by 20 per cent in the last decade.
There are over 41,000 new cases of breast cancer each year in the UK, causing one-third of all cancer cases in British women.
