Background: Cancer is a leading cause of death worldwide, with breast cancer being the most prevalent type of cancer among women. It occurs when abnormal cells in the breast grow uncontrollably. Anxiety and depression are common psychological responses among breast cancer patients, which can significantly impact their quality of life (QoL). This study aims to evaluate the prevalence of anxiety in breast cancer patients and explore the effectiveness of Progressive Muscle Relaxation (PMR) therapy in alleviating anxiety and improving QoL. Methods: A review of the literature published between 2015 and 2025 was conducted using databases such as PubMed, Google Scholar, Scopus, ResearchGate, and CINHAL. The search utilized MeSH terms including “Breast Cancer,” “Anxiety,” “Quality of Life,” and “Progressive Muscle Relaxation.” A total of 24 studies that met the inclusion criteria were included in this narrative review. Results: The majority of studies reported a high prevalence of anxiety and depression among breast cancer patients, which negatively affects their quality of life. Several studies highlighted the positive impact of complementary therapies, including PMR, in improving psychological well-being and health-related quality of life (HRQoL) among these patients. Conclusion: Progressive Muscle Relaxation (PMR) is a simple and effective therapy that can help reduce anxiety in breast cancer patients. Combined interventions using PMR and other complementary therapies may further enhance the psychological and physical health of patients. A longer duration of therapy (12-14 weeks) is recommended for optimal results.
