PHILADELPHIA -- If you feel that you are fated for cancer, your belief could turn into a self-fulfilling prophecy. According to a national survey of more than 6,000 U.S. adults published in the May issue of Cancer Epidemiology, Biomarkers & Prevention, a substantial number of American adults hold fatalistic beliefs about cancer and are correspondingly less likely to take basic steps to lower their cancer risk, such as exercising, quitting smoking and eating a healthy diet rich in fruits and vegetables.
