Being satisfied with their quality of life may actually help people with cancer live longer. That’s the result of a study conducted by researchers working with the North Central Cancer Treatment Group, a research organization sponsored by the National Cancer Institute. Study subjects included more than 3,700 patients who had a variety of late-stage cancers and were taking part in clinical trials. All were asked one question: On a scale of 0 to 10, how would you rate your quality of life? Researchers compared responses with patients’ overall survival statistics. They found that quality of life was a strong predictor of survival and suggest that addressing patients’ decreased feelings of well-being can prolong life. Quality of life generally includes physical, psychological, social and spiritual factors.
