BREAST ASSYMETRY PREDICTS BREAST CANCER
Women who go on to
develop breast cancer tend to have breasts that are less symmetrical than women
who don't develop the cancer. A study published in Breast Cancer Research
reveals that breast asymmetry could be a reliable independent predictor of
breast cancer
The study found that
the relative odds of developing breast cancer increased by 1.5 with each 100ml
increase in breast 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 the mammography, but later on
developed the disease. The control group consisted of 252 women matched for age
who underwent mammography at the same time, but did not develop breast cancer.
Scutt et al.'s results
show that, at the time the mammography was done, women who went on to develop
breast cancer had higher breast volume asymmetry than controls. The authors
found that the relative odds of breast cancer increased by 1.5 for a 100ml
increase in absolute breast volume asymmetry, after adjusting for other
potential risk factors. They conclude that breast asymmetry is a significant
independent predictor of breast cancer, and could be a reliable indicator of
future breast disease.
