Having a positive outlook may help prevent breast cancer, while getting divorced or losing a loved one may increase the risk, suggests an Israeli study that compared the mental outlook and life events of 255 breast cancer patients and 367 healthy women.
The researchers found that a generally positive outlook was associated with a 25 percent reduced risk of breast cancer, while experiencing one or more traumatic life events -- such as the loss of a parent or spouse -- was associated with a more than 60 percent increased risk, BBC News reported.
