Left-handers More ProneTo Breast Cancer

Young women who are left-handed may have a higher risk of developing breast cancer, according to a new Dutch study published in the British Medical Journal.

The researchers looked at the association between handedness and breast cancer incidence in 1,500 initially healthy women born between 1932 and 1941.

"Our aim was to try to shed some more light on a possible cause for breast cancer, and we were able to show that left-handedness may play a role," said Dr. Cuno Uiterwaal, senior author of the study and assistant professor of clinical epidemiology at the Julius Center for Health Sciences and Primary Care, University Medical Center in Utrecht, the Netherlands.

Overall, left-handed women were at a 39 percent higher risk for developing breast cancer, the researchers found. The health risk for premenopausal cancer in left-handed women was more than twice as high.

Researchers emphasized that left-handed women should not be unduly worried based on these findings, nor should they be screened more closely for the disease. They said it is far too early to think about practical applications.

The overall five-year survival rate for women diagnosed with breast cancer is now 88 percent, and the 10-year survival rate is 80 percent, according to the American Cancer Society.
