This observation was maintained when other risk factors such as age, alcohol and tobacco consumption, family history of cancer, and work situation were controlled statistically. No relationship was found between a high depression value on the MMPI and mortality from any other diseases. Whereas the association with incidence was apparent only during the first ten years of follow-up, the association with mortality was observed for the full 20 years of follow-up. The data from this study did not support the hypothesis that psychologic repression would be associated with an increased risk of cancer, as it might be interpreted from the summarized findings of other investigators in Table 2. However, recent prospective epidemiologic studies call into question the causal connection between depressive symptoms and cancer morbidity and mortality. antibiotics levaquin
As Table 2 shows, personality traits in lung cancer patients have been studied using many different psychologic and social variables. The studies are based on different theoretical concepts, and as a result, many different instruments have been used. The hypotheses are tested against different controls (healthy individuals and persons with other chest diseases). Therefore, it is difficult to use these findings to describe a consistent psychosocial risk profile for lung cancer patients, and comparison with similar studies in other cancer sites and chronic diseases does not show any specific psychosocial pattern for lung cancer. We find no consistent evidence to support the belief that there is a “lung cancer” or “cancer personality,” as some have claimed.
