Watch Out for Cancer Lefties

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.


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.
Okay, so what happens if you’re ambidextrous?

Wow...they are really reaching on this one! Being a 'left-handed woman' myself....I'd like to think positively-that I have a very good chance of living to 130 yrs old.
