Applying Lifestyle Medicine to Enhance Cancer Survivorship and Patient Well-being.

Lifestyle medicine provides an evidence-based framework for addressing the complex and evolving needs of patients across the cancer continuum. Built on 6 pillars, physical activity, nutrition, sleep, stress management, social connectedness, and avoidance of risky behaviors, lifestyle medicine is supported by major organizations as a core component of comprehensive oncology care. Cancer therapies frequently disrupt dietary intake through treatment-related toxicities, while long-term survivorship is often complicated by metabolic dysfunction and weight change. Current guidance emphasizes whole food-based dietary patterns and limiting ultra-processed foods, red meat, and alcohol, although evidence for specific dietary strategies in recurrence prevention remains mixed. Regular physical activity improves quality of life, reduces treatment-related symptoms, and is associated with improved survival outcomes. Sleep disturbances, psychosocial stress, and social isolation are also prevalent and linked to immune dysregulation, inflammation, and worse clinical outcomes; evidence-based interventions such as cognitive behavioral therapy and mindfulness-based stress reduction can improve psychological and functional well-being. Tobacco and alcohol cessation remain critical priorities given their associations with treatment complications, recurrence, and mortality. Effective implementation requires coordinated, multidisciplinary care models that integrate behavioral health, rehabilitation, nutrition, and community resources. Embedding longitudinal, patient-centered lifestyle interventions into oncology practice may improve survivorship outcomes and overall health.
