CHICAGO — In a landmark clinical trial that could change how doctors support cancer recovery, researchers have found that a consistent walking routine can significantly lower the chances of colon cancer returning after treatment.
According to results presented at the American Society of Clinical Oncology (ASCO) meeting this week, patients who engaged in a structured exercise program experienced a 28% lower risk of cancer recurrence or death compared to those who did not.
“We approve drugs that have the same and in some cases less of a benefit than this,” said Dr. Julie Gralow, Chief Medical Officer of ASCO. “That’s why these findings are so powerful.”
Research Reveals Life-Saving Benefits of Exercise for Colon Cancer Patients
The Study: Simple Routine, Big Results
The clinical trial observed nearly 900 individuals with Stage 3 or high-risk Stage 2 colon cancer, each of whom had completed chemotherapy. Participants were divided into two groups: one received standard care, while the other joined a supervised fitness program.
Those in the exercise group walked briskly for 45 minutes a day, four days a week — totaling around 10 MET hours per week, a standard measurement for aerobic effort.
Over an 8-year follow-up period, the researchers noted clear benefits for the active group:
- 28% reduced risk of recurrence or death
- Better quality of life reported
- Reduced fatigue and improved physical function
“This is a lifestyle intervention that anyone with access to safe walking spaces can begin right away,” said Dr. Jeffrey Meyerhardt, a gastrointestinal oncologist and co-lead of the trial.
What This Means for Chicago Suburbs
Colon cancer is among the top three cancer types diagnosed in Illinois each year, particularly affecting adults over 50. With suburban families often supporting aging parents or loved ones in treatment, this research is a hopeful reminder of how low-cost habits can lead to major health improvements.
Several Chicago-area hospital systems, including NorthShore University HealthSystem, Rush University Medical Center, and Advocate Aurora Health, offer post-treatment survivorship programs that include walking clubs, rehab, and group fitness sessions.
“Movement is medicine. We encourage survivors to start small and build up,” shared Marsha Daniels, a physical therapist at Rush Cancer Rehab.
Not Just Physical Health — Mental Boosts Too
Beyond lowering recurrence risk, study participants reported a strong uplift in mood, mental clarity, and motivation. For many patients, incorporating a walking routine offered structure, a sense of control, and social connection during a period often filled with medical uncertainty.
“I walked for my mind as much as for my body,” said Gloria Benson, a participant from the Midwest. “After treatment, walking gave me back a rhythm and helped me heal.”
What You Can Do: Getting Started
If you or a loved one is recovering from colon cancer or at risk, here are immediate steps you can take:
- Start with short walks: Even 15–20 minutes a day can lead to health benefits.
- Track your activity: Use a simple step counter or phone app.
- Look for support: Many suburbs have senior centers or park districts with walking groups.
- Consult your doctor before starting a fitness routine, especially post-treatment.

The Bigger Picture
As funding debates rage over access to medication and insurance gaps, this study re-emphasizes the value of evidence-based, low-cost lifestyle strategies. It also empowers patients to take part in their healing.
“When we say 45 minutes of walking, we’re not just talking about exercise — we’re talking about hope, community, and proactive recovery,” said Dr. Gralow.
