With more than one million women diagnosed with breast cancer each year, scientists have released a report that states women are over twice as likely
to contract breast cancer before menopause if they are left handed. Cuno Uiterwaal, an assistant professor at the University Medical Centre in Utrecht
in the Netherlands and a team of researchers studied 12000 healthy women born between 1932 and 1941 and found "Left handedness is associated with
breast cancer, most specifically pre-menopausal breast cancer,".
EFT-HANDED women are more than twice as likely as right-handers to suffer from breast cancer before reaching menopause, Dutch scientists said
More than a million women are diagnosed with breast cancer worldwide each year. Three-quarters of cases occur after menopause, which usually begins
around the age of 50.
"If we take pre-menopausal and post-menopausal breast cancer then there was a 40 per cent increased risk," Professor Uiterwaal said of left-handed
But when they spilt it further the scientists found most of the excess risk was in breast cancer before the menopause.
"We found that left-handed women are more than twice as likely to develop pre-menopausal breast cancer as non-left handed women," the researchers said
in the report published online by the British Medical Journal.
"Although the underlying mechanisms remain elusive, our results support the hypothesis that left handedness is related to increased risk of breast
cancer," the researchers added.

I would not have thought that hand preference would have much to do with the incident of Breast cancer, so this study surprised me. I don't know
whether there is another underlying reason for the breast cancer that is also linked to left handers but it doesn't seem right to say, oh well you
have breast cancer because you are left handed.
I would like to see more testing done and different methods applied before this statement and report is taken as gospel
I personally am left handed and haven't reached menopause but I am not going to start getting worried over this report as there are many many many
right handed women suffering the same fate of breat cancer before menopause.
