The relative odds of breast cancer increased by 1.5 for a 100 ml increase in absolute breast volume asymmetry after adjusting for potential other risk factors, a new study found.
Breast cancer is more likely to occur in women who have uneven breasts, according to
a study published in
Breast Cancer Research, suggesting that breast asymmetry could be a reliable independent predictor of the disease. The relative odds of developing breast cancer increased by 1.5 with each 100 ml increase in breast asymmetry, the study found.
Breast Volume Asymmetry
Diane Scutt from the University of Liverpool, UK and colleagues studied the mammograms of 252 women who did not have breast cancer at the time of mammography, but developed the disease later.
The control group consisted of 252 women matched for age who underwent mammography at the same time but did not develop breast cancer.
At the time the mammography was done, the women who went on to develop breast cancer had higher breast volume asymmetry than the controls, Scutt et al's results show.
Significant Independent Predictor
The relative odds of breast cancer increased by 1.5 for a 100 ml increase in absolute breast volume asymmetry after adjusting for potential other risk factors, the authors found.
Breast asymmetry is a significant independent predictor of breast cancer, they conclude, and could be a reliable indicator of future breast disease. |
