The Impact of Yoga on the Immune System of Cancer Patients: A Scoping Review of Current Evidence

Background: Cancer is a growing problem worldwide, and new strategies for its management and treatment are  required. The immune system plays a crucial role in cancer progression and the response to treatment. Recent studies  have demonstrated that practicing yoga can positively affect the immune system. This review aimed to examine the  impact of yoga on immune parameters in patients with cancer. Methods: We conducted literature searches across several scientific databases for trials published from 2014 to 2023.  Studies were selected based on specific criteria, including randomized controlled trials involving yoga interventions  with quantitative outcome assessments. Results: Eight studies met our inclusion criteria. These findings suggest that practicing yoga can significantly improve  immune function in patients with cancer. Key findings include reductions in inflammatory cytokines, improvements  in natural killer cell counts, and modulated gene expression related to immune cell survival. Specific studies have  demonstrated benefits in reducing stress and fatigue, enhancing overall quality of life (QoL), and immunological  benefits. Conclusion: This review indicates that yoga interventions hold substantial promise in enhancing immune function  and overall QoL in patients with cancer.
