Exercise and Cancer Treatment: How Movement Can Reduce Side Effects and Improve Recovery

New Research Confirms It: Exercise Can Support Your Cancer Recovery

A groundbreaking 2025 analysis published in the British Journal of Sports Medicine has confirmed what oncologists and physical therapists have long suspected — exercise during and after cancer treatment offers major benefits, including:

• Reduced heart and nerve damage from treatment
• Less fatigue and brain fog
• Improved physical function and mental well-being

The study, the largest of its kind, analyzed over 180 clinical trials and found that structured physical activity, including aerobic exercise, resistance training, and yoga, can significantly reduce the side effects of common cancer treatments like chemotherapy, radiation, and hormone therapy.

So what does this mean for you — or a loved one — going through cancer treatment?

Let’s break it down.

How Exercise Helps During and After Cancer Treatment

Cancer treatments are powerful, but they can take a toll on your body. Some common side effects include:

• Fatigue and exhaustion
• Cognitive issues (also called "chemo brain")
• Nerve pain or numbness (neuropathy)
• Increased risk of cardiovascular disease
• Weakness or muscle loss
• Anxiety and depression

Exercise works by improving circulation, enhancing oxygen flow, strengthening muscles, and releasing mood-lifting endorphins. When done safely under medical supervision, movement can counteract the physical and mental impact of treatment.

What Kind of Exercise Works Best?

According to the study, the most effective types of exercise include:

• ‍Aerobic activity: Walking, swimming, cycling — improves stamina and heart health
• ‍Strength training: Light weights or resistance bands — helps rebuild muscle mass
• ‍Yoga and stretching: Supports flexibility, reduces anxiety, and relieves joint pain

You don’t need to run a marathon. In fact, 20–30 minutes of light to moderate activity, 3–5 times per week, is enough to see benefits.
