The Cancer Blog relays some information claiming left-handed women are more likely to develop breast cancer than their right-handed counterparts—really weird. Take a look:
This left-handed conclusion, published in the journal Epidemiology, comes from the study of 12,000 women in the Netherlands whose medical histories were followed for 13 years. Discounting all other factors -- lifestyle, environment, and other disease -- left-handers came up with a risk of breast cancer 1.39 times that of right-handers. For pre-menopausal women, the figure climbed to 2.41.Okay, so what happens if you’re ambidextrous?
When considering all sorts of illness, left-handed women had a 70 percent higher chance of contracting any cancer and a 30 percent higher chance of a fatal disease of the circulatory system. It's not just breast cancer -- it's any number of health conditions that may be linked to regular use of the left hand.
Scientific reactions on this topic are mixed.
