Abstract
IntroductionThe aim of this study was to identify and analyze the stress factors and the level of stress a year preceding the onset of breast cancer and depression in the studied female patients.MethodsThe research in this work was mostly prospectively (clinical and analytical). During the research, Scale of Life Events‐Paykel was applied. Stressful life events differed significantly between the groups. In the studied group, the following events were significantly more prevalent: partner infidelity (χ 2 = 12.663; p < .001), failure at work (χ 2 = 44.429; p < .001), and spontaneous abortions or stillbirths (χ 2 = 13.818; p < .001).ResultsAccording to the results of this study, stressful life events differed significantly between the observed groups. These stressful life events had a significant impact on the increase of risk for breast cancer, as well as on depressivity. Afterward, adaptive neuro‐fuzzy inference system was used for prediction of the Paykel's Life Event according to Fisher's exact test.ConclusionThe obtained results could be of practical usage for improving stress behavior of the patients with breast cancer and depression.
Highlights
The aim of this study was to identify and analyze the stress factors and the level of stress a year preceding the onset of breast cancer and depression in the studied female patients
The obtained results could be of practical usage for improving stress behavior of the patients with breast cancer and depression
The results demonstrated that women who frequently or continually experienced stress had a risk for breast cancer similar to that in women who never experienced any stress or experienced it only occasionally
Summary
The aim of this study was to identify and analyze the stress factors and the level of stress a year preceding the onset of breast cancer and depression in the studied female patients. Stressful life events differed significantly between the groups. The following events were significantly more prevalent: partner infidelity (χ2 = 12.663; p < .001), failure at work (χ2 = 44.429; p < .001), and spontaneous abortions or stillbirths (χ2 = 13.818; p < .001). Results: According to the results of this study, stressful life events differed significantly between the observed groups. These stressful life events had a significant impact on the increase of risk for breast cancer, as well as on depressivity. Conclusion: The obtained results could be of practical usage for improving stress behavior of the patients with breast cancer and depression. Chronic stress is the result of poor adaptive response to a sequence of unpleasant and upsetting long-term life situations which tend to exhaust human defense mechanisms. Individuals with insufficient (deficient) defense mechanisms in stressful situations tend to react with
