Breast cancer risk doubled for left-handed women
LEFT-HANDED women are more at risk from breast cancer, according to new research published today.
A team in the Netherlands looked at the relationship between left or right-handedness and cases of breast cancer in more than 12,000 middle-aged women who were born between 1932 and 1941.
The researchers also took body measurements and assessed risk factors such as economic status, smoking habits, family history of breast cancer and reproductive background.
The study, published online by the British Medical Journal, found left-handed women were more than twice as likely to develop pre-menopausal breast cancer as right-handed women.
