Exercise has long been recommended for cancer patients to ease fatigue, brain fog, and surgical recovery. But the CHALLENGE trial — which assigned colon cancer patients to a 3-year structured exercise program with 50–70 hours of support — has elevated the conversation entirely: exercise can now be shown to reduce recurrence and extend survival. Experts say this puts exercise "in a whole new evidentiary category."

The challenge now is translating trial results into real-world oncology practice. Clinic time is tight, reimbursement is scarce, and only 27% of patients feel capable of increasing their activity on their own. Experts recommend a simple framework: assess, advise, and refer. Oncologists don't need to prescribe workout plans — just asking "How many days per week are you active?" opens the door, and a trusted clinician's recommendation is one of the strongest predictors of whether a patient will actually exercise.

Key Takeaways:

• A clinician's recommendation is one of the strongest predictors of patient exercise uptake — the conversation matters
• Use the "assess, advise, refer" framework; avoid prescribing specific plans, and opt for collaborative goal-setting instead
• Free and low-cost referral options exist, including the ACSM's Moving Through Cancer directory (~2,300 programs), YMCA's LIVESTRONG program, and virtual platforms like Moving For Life

Why it matters: With ASCO guidelines being updated and the American College of Surgeons proposing exercise oncology standards potentially finalized by 2028, exercise is on track to become a formal pillar of cancer care — and oncologists are on the front lines of making it happen.
