Full context:   From the study above, several conclusions have been made. A relationship between personality and cancer exists, along with a relationship between personality and coronary heart disease. Personality type acts as a risk factor for diseases and interacts synergistically with other risk factors, such as smoking and heredity. It has been statistically proven that behavior therapy can significantly reduce the likelihood of cancer or coronary heart disease mortality. Studies suggest that both body and mental disease arise from each other. Mental disorders arise from physical causes, and likewise, physical disorders arise from mental causes. While Type A personality did not show a strong direct relationship between its attributes and the cause of coronary heart disease, other types of personalities have shown strong influences on both cancer-prone patients and those prone to coronary heart disease.
