What is Exercise Oncology?
Exercise oncology is the study and application of physical activity in the prevention, treatment, and recovery of cancer. Research has shown that exercise can play a crucial role in improving the quality of life, reducing treatment side effects, and even enhancing survival rates for cancer patients and survivors.
Benefits of Exercise for Cancer Patients
- During Cancer Treatment
- Reduces Fatigue: Regular movement helps combat cancer-related fatigue, a common side effect of treatments like chemotherapy and radiation.
- Maintains Muscle Mass & Strength: Prevents muscle wasting due to inactivity or treatment side effects.
- Improves Mood & Mental Health: Exercise releases endorphins, reducing anxiety, depression, and stress.
- Enhances Cardiovascular Health: Counteracts the negative impact of treatments that may weaken the heart and blood vessels.
- Boosts Immune Function: Supports the body’s ability to fight infections.
- Post-Treatment Survivorship
- Reduces Recurrence Risk: Studies suggest that regular exercise lowers the risk of recurrence for several types of cancer, including breast, colon, and prostate cancer.
- Improves Bone Health: Weight-bearing exercises help counteract bone density loss from treatments like hormone therapy.
- Enhances Cognitive Function: Helps manage “chemo brain” (cognitive fog associated with cancer treatment).
- Regulates Body Weight: Supports a healthy weight, reducing inflammation and hormonal imbalances that may contribute to cancer recurrence.
- Cancer Prevention
- Lowers Cancer Risk: Regular physical activity is linked to reduced risk of several cancers, including breast, colon, lung, and endometrial cancer.
- Regulates Hormones: Exercise helps balance estrogen, insulin, and other hormones that can impact cancer development.
Reduces Chronic Inflammation: Physical activity decreases systemic inflammation, which is linked to cancer progression.
Exercise Guidelines for Cancer Patients
The American College of Sports Medicine (ACSM) and other organizations recommend:
General Recommendations
- Aerobic Exercise: 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity per week (e.g., walking, cycling, swimming).
- Strength Training: At least 2 days per week, focusing on major muscle groups (e.g., resistance bands, bodyweight exercises, light weights).
- Flexibility & Balance: Yoga, stretching, and balance exercises help maintain mobility and reduce fall risk.
- Personalized Approach: Programs should be tailored to the individual’s treatment stage, side effects, and fitness level.
Precautions
- Fatigue Management: Adjust intensity and duration based on energy levels.
- Bone Metastases: Avoid high-impact exercises that increase fracture risk.
- Compromised Immune System: Choose clean and controlled environments (avoid crowded gyms).
- Peripheral Neuropathy: Opt for stable, low-impact activities if experiencing numbness or tingling in extremities.
Exercise Oncology in Clinical Practice
- Supervised Programs: Many cancer centers now offer supervised exercise programs led by specialists in exercise oncology.
- Rehabilitation & Physical Therapy: Some cancer survivors require rehab programs to regain strength, coordination, and endurance.
- Behavioral Support: Incorporating counseling and support groups can enhance adherence to an exercise routine.
Exercise is a powerful tool in cancer care, providing numerous physical and mental health benefits. Whether before, during, or after treatment, incorporating safe and appropriate physical activity can enhance well-being, reduce side effects, and improve long-term health outcomes. Always consult with a healthcare provider or a certified exercise oncology specialist before starting an exercise program.
