Exercise During Cancer Treatment: What Science Says About Strength, Recovery, and Healing

Cancer treatment places enormous stress on the body — physically, emotionally, and mentally. Many patients ask the same question:

“Is it safe to exercise during cancer treatment?”

According to leading oncology research, the answer is often yes, and it can be incredibly beneficial when done correctly.

In a powerful expert discussion, exercise oncology researcher Dr. Kerry Courneya, PhD, explains how movement plays a meaningful role in cancer care, recovery, and survivorship.

Can You Exercise During Cancer Treatment?

For many years, rest was the default recommendation during chemotherapy and radiation. Today, science tells a different story.

Benefits may include:

• Improved physical strength and endurance
• Reduced treatment-related fatigue
• Better mood and emotional well-being
• Improved ability to tolerate treatment
• Support for long-term recovery

Importantly, exercise during cancer treatment does not mean intense workouts or pushing through exhaustion. It means intentional, gentle movement tailored to the individual.

What Research Says About Exercise and Cancer Recovery

In the podcast, Dr. Courneya explains that physical activity is one of the most studied lifestyle interventions in oncology.

Large studies suggest that regular exercise may:

• Improve quality of life during treatment
• Help preserve muscle mass and physical function
• Support immune and metabolic health
• Potentially reduce the risk of recurrence for certain cancers, including breast and colon cancer

Some research estimates that up to 40% of cancers may be influenced by lifestyle factors, including physical activity, nutrition, and smoking status.

While exercise is not a cure, it is increasingly viewed as a supportive therapy alongside conventional treatment.

Best Types of Exercise During Chemotherapy and Radiation

Not all exercise is the same, and during cancer treatment, less is often more.

Dr. Courneya emphasizes that the most effective programs prioritize consistency, safety, and personalization.

Commonly recommended activities include:

• Walking at a comfortable pace
• Gentle strength training with light resistance
• Stretching or mobility exercises
• Balance and posture work
• Low-impact activities like stationary cycling or water exercise

The goal is not performance. The goal is maintaining function, circulation, and confidence in the body.

How to Start Exercising Safely During Cancer Treatment

Before beginning any exercise routine, patients should always:

• Talk with their oncology team
• Listen closely to daily energy levels
• Stop if pain, dizziness, or unusual symptoms occur

Starting points may be as simple as:

• 5–10 minutes of walking
• Gentle stretching once per day
• Light movement on “good days,” rest on harder days

Progress should be gradual and flexible. Your body is already doing hard work.

Supporting the Body Beyond Exercise

Movement is one part of supporting the body through cancer treatment. Skin, nerves, and connective tissue are also under stress — especially during chemotherapy and radiation.

Many patients experience:

• Radiation-related skin irritation
• Chemotherapy-related dryness or sensitivity
• Hand-foot discomfort
• Scalp and hair changes

At Dermavitality, education and product development are guided by oncology nursing experience and real patient needs. Our goal is to help patients feel supported — not overwhelmed — throughout treatment and recovery.

Exercise as Empowerment During the Cancer Journey

Cancer can make people feel disconnected from their bodies. Gentle, intentional movement helps many patients rebuild trust in their strength, even during treatment.

As Dr. Courneya explains, exercise is not about control — it’s about participation in healing.

Combined with compassionate medical care, supportive skincare, nutrition, and rest, movement becomes another way to care for yourself during a challenging season.
