In the face of chronic disease, an arm chair analysis of the cause can often lead to a discussion of personality types and statements like, "Her depression lead to her cancer." A new Dutch study indicates that being a type A or type B personality doesn't lead to breast cancer.
This new study followed 9,700 women for thirteen years. The participants, all 43 years or older, were given a personality survey with questions about different traits including anxiety, anger, depression, optimism, and the ability to express emotions.
After 13 years, 271 women were diagnosed with breast cancer. The researchers, however, could find no correlation between personality and disease. So be you type A or type B, or any variation in between, your personality is not a factor in developing breast cancer. Red meat on the other hand, is quite a different story.
