- The CHALLENGE Trial found a structured exercise program after treatment lowered recurrence, a new primary cancer, or death by 28% in stage 2 and 3 colon cancer patients.
- The same group showed a 37% lower risk of death from any cause, highlighting survival benefits beyond recurrence.
- Experts say exercise should be integrated into standard cancer care alongside surgery, radiation, and chemotherapy.
- Researchers are still studying how exercise affects cancer, including immune surveillance and inflammation reduction.
- The trial examined potential hormonal and metabolic pathways, such as reduced estrogen and improved insulin sensitivity.
- Experts note limited access to exercise oncology programs and often no insurance coverage for these services.
- The study plans to analyze participants’ blood samples in future phases to identify biological changes associated with exercise.
- Medical groups are forming dedicated exercise oncology programs to help cancer patients during treatment and recovery.
- The CHALLENGE Trial is seen as a turning point for exercise oncology, expanding the potential role of exercise in cancer care.
