Introduction 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. Methods The 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 (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. Afterward, adaptive neuro‐fuzzy inference system was used for prediction of the Paykel's Life Event according to Fisher's exact test. Conclusion The obtained results could be of practical usage for improving stress behavior of the patients with breast cancer and depression. Show more
