ObjectiveThe article aims to assess the role of stress and anxiety in relation to the level of emotional control among cancer patients. Currently cancer ranks second, after cardiovascular disease, as the most common cause of death. Moreover, it is predicted that in the coming years, cancer will become the leading cause of death worldwide. This is due to the extended lifespan of the population and also to the presence of carcinogenic factors in the surrounding environment. The emergence of cancer is a significant stressor that affects individuals in diverse ways, leading to cognitive, behavioral, and emotional consequences. In line with the adopted aim, emotional issues are the chosen area of exploration in this article.MethodsThe study included 102 patients. The differences between the patients' results according to various scales and the results produced by the validation group data were examined using one‐sample t‐tests. The relationships between the quantitative variables were determined using Spearman's rho coefficients, and the relationships between the quantitative and qualitative variables were verified using Kruskal‐Wallis tests.ResultsThe participants exhibited higher anxiety suppression levels than individuals in the normalization group. They sought emotional support more frequently than the average person in the population, turned to religion, engaged in other such activities, lived in denial more often, discontinued activities, and displayed a sense of humor less frequently. The more frequently they controlled their anger, the less they sought emotional and instrumental support, catharsis, and attempted to accept the situation and cease being active. Additionally, controlling anxiety, sadness, and depression coexisted with self‐blame, denial, and compensatory actions.ConclusionsCancer patients face intense anxiety. Emotional and instrumental support, along with the ability to express and manage emotions, are crucial for these patients, especially within the context of facing the challenge of cancer. Finding constructive ways to express strong and difficult emotions prevents their accumulation and reduces the need for emotional suppression. Preventive actions should be oriented toward supporting the emotional competencies of patients.
