Though exercise isn’t considered a treatment for CRC, engaging in at least three hours of moderate physical activity per week can increase survival rates in patients with non-metastatic CRC (cancer that hasn’t spread to other areas).[1] Cognitive interventions — such as cognitive behavioral therapy or relaxation techniques — can improve cancer-related fatigue and both short- and long-term quality of life, while social support groups can improve short-term quality of life.[2] Immunonutrition combines enteral or parenteral nutrition formulas with additional arginine, glutamine, and omega-3 fatty acids, and could improve post-operative recovery compared to the plain formulas.[3]
