Exercise Benefits Beyond Weight Loss
- Exercise reduces cancer risk regardless of obesity or smoking status.
- This suggests multiple mechanisms beyond weight management are at play.
Maximize Exercise Intensity
- For cancer prevention, prioritize higher intensity exercise over just light jogging.
- Increasing intensity, frequency, or duration all contribute to greater risk reduction.
Preemptive Benefits of Exercise
- Pre-diagnosis exercise may improve cancer outcomes, independent of post-diagnosis activity.
- It might alter tumor biology, delay onset, or simply prepare you for treatment.
