A Powerful Shift in Cancer Care
For decades, cancer patients undergoing chemotherapy or radiation were often advised to rest and conserve energy. Today, that paradigm is rapidly changing.
A recent scoping review of 40 studies examining exercise during adjuvant cancer therapy—including chemotherapy and radiotherapy—provides compelling evidence that exercise is not only safe, but highly beneficial during active treatment.
This growing body of research signals an important shift: exercise is becoming a core component of modern cancer care.
What Happens to the Body During Treatment
Cancer treatments are life-saving—but they often come with significant side effects, including:
- Severe fatigue
- Loss of muscle mass and strength
- Reduced cardiovascular fitness
- Anxiety and depression
- Cognitive decline (“chemo brain”)
- Decline in overall quality of life
These changes can begin early and may persist long after treatment ends.
The key question is no longer whether these side effects occur—but what we can do to reduce them.
Exercise: A Proven Intervention During Treatment
This review highlights that several types of exercise are consistently used and studied during treatment:
- Aerobic exercise (walking, cycling)
- Resistance training (strength-building exercises)
- Combined programs (aerobic + strength)
- Multimodal programs (including balance, flexibility, mobility)
- Yoga and relaxation techniques
The findings are clear: patients who exercise during treatment experience meaningful benefits.
Key Benefits for Cancer Patients
1. Reduced Fatigue
Cancer-related fatigue is one of the most common and debilitating symptoms. Exercise has been shown to significantly reduce fatigue levels—often more effectively than rest.
2. Improved Strength and Physical Function
Maintaining muscle mass and strength helps patients stay independent and better tolerate treatment.
3. Better Cardiovascular Fitness
Exercise helps preserve heart and lung function, which can decline during therapy.
4. Improved Mental Health
Exercise reduces anxiety and depression and promotes a sense of well-being and control.
5. Enhanced Quality of Life
Patients who remain active consistently report better overall quality of life.
6. Potential for Improved Treatment Tolerance
Some studies suggest that exercise may help patients complete treatment with fewer interruptions or complications.
What This Means for Cancer Patients
If you are undergoing chemotherapy or radiation, this research delivers an important message:
👉 You do not need to wait until treatment ends to start exercising.
👉 You should not assume rest is always the best strategy.
Instead, appropriate, guided exercise can be one of the most effective tools you have to maintain your strength, energy, and well-being during treatment.
Even modest activity—such as walking, light resistance training, or yoga—can make a meaningful difference.
What This Means for Cancer Care Providers
For oncologists, nurses, and the broader cancer care team, this review reinforces a critical responsibility:
Exercise should be prescribed as part of treatment—not just suggested.
Key takeaways for providers include:
- Normalize exercise during treatment as safe and beneficial
- Individualize recommendations based on patient condition and treatment
- Collaborate with rehabilitation professionals (physical therapists, exercise specialists)
- Monitor key outcomes such as fatigue, function, and quality of life
Exercise is no longer optional supportive care—it is evidence-based therapy.
Barriers—and Opportunities
Despite strong evidence, many patients are still not receiving exercise guidance during treatment.
Common barriers include:
- Lack of awareness
- Fear of overexertion
- Limited access to supervised programs
However, the review highlights that home-based and online exercise programs are effective and feasible, expanding access for many patients.
CancerFitness.org Bottom Line
This study adds to a rapidly growing body of evidence:
👉 Exercise during chemotherapy and radiation is safe.
👉 Exercise reduces treatment side effects.
👉 Exercise improves physical and emotional outcomes.
Most importantly: Exercise gives patients a way to actively participate in their own care.
A Strong Call to Action
If you are a cancer patient:
Talk to your care team today about starting a safe, individualized exercise program—even during treatment.
If you are a cancer care provider:
Make exercise a routine part of your treatment discussions and referrals.
Final Thought
Cancer treatment is not just about eliminating disease—it is about preserving function, dignity, and quality of life.
Exercise is one of the most powerful tools we have to achieve all three.
