How Happiness May Prevent Breast Cancer?

According to a new study, happiness and optimism may play a role against breast cancer while adverse life events can increase the risk of developing the disease.

A total of 622 women between the ages of 25 and 45 were interviewed: 255 breast cancer patients and 367 healthy women. The findings of the study show that there was a clear link between outlook and risk of breast cancer, with optimists 25 percent less likely to have developed the disease.
