Background: Breast cancer (BC) is one of the highest incidence rates in Lebanon. Previous studies had focused scarcely on the unconscious protective shield of patients with BC or BC survivors against cancer, while only some studies had focused on the relationship between defense mechanisms (DMs) and high adaptation with the disease process and progress. Therefore, this study aimed to investigate the reaction of inpatients with BC toward the disease by measuring DMs in the Lebanon context. Methods: Seventy inpatients with BC were recruited randomly from six hospitals. Their DMs were measured using the Defense Mechanism Rating Scale. Moreover, the Relationship Anecdotes Paradigm (RAP) was used with three recent life vignettes of initial diagnosis, family, and daily life. The data were analyzed using repeated measure ANOVA, Wilcoxon rank-sum test, and Spearman's rank. Results: Patients with stage 2 BC used more high-adaptive defense levels than patients with stage 4 BC who used more minor image distorting defense levels. Moreover, patients with stage 2 BC used more self-observation and undoing, while patients with stage 4 BC used more devaluation. Conclusion: The severity of BC, the age of carriers, and the social status may lead to higher use of DMs, at the level of the individual defense and the hierarchal or the tripartite levels.
