How Exercise Can Be Your Secret Weapon Against Cancer – Insights from Dr. Kerry Courneya

 

Every year, 2 million Americans hear the devastating words: “You have cancer.” But here’s the shocking truth: nearly 40% of those cases could have been prevented, and exercise is one of the most powerful tools we have to fight back.

At MakeLifeEasy.com, we’re passionate about helping you live a healthier, more active life. That’s why we’re diving into the science of exercise and cancer prevention, inspired by a recent conversation with Dr. Kerry Courneya, a leading expert in exercise oncology. Whether you’re looking to reduce your cancer risk, support a loved one through treatment, or improve your overall health, this blog will show you how movement can make a life-changing difference.

Exercise: A Lifesaving Habit

While smoking, obesity, and alcohol are well-known cancer risk factors, exercise is often overlooked. Yet, research shows that regular physical activity not only lowers cancer risk but also strengthens the body for treatment, enhances drug effectiveness, and reduces recurrence rates.

Here’s how exercise impacts every stage of the cancer journey:

1. Cancer Prevention

Exercise is one of the most powerful lifestyle factors for reducing cancer risk. Studies show that regular physical activity can significantly lower the risk of at least 8-10 types of cancer, including:

  • Breast cancer (6-10% lower risk)

  • Colon cancer (8-14% lower risk in men)

  • Endometrial cancer (10-19% lower risk)

The more you move, the greater the protective effect. While 150 minutes of moderate-intensity exercise per week is the baseline recommendation, increasing to 300 minutes provides even greater benefits. And here’s the kicker: vigorous exercise may offer enhanced protection in less time, making high-intensity workouts a time-efficient way to lower your risk.

2. Prehabilitation: Preparing for Treatment

If you or a loved one is facing a cancer diagnosis, prehabilitation—strengthening the body before treatment—can make a world of difference. Patients who are physically fit before treatment tend to experience fewer complications, better survival rates, and faster recovery times.

Prehabilitation programs typically focus on:

  • Aerobic exercise to boost cardiovascular and lung function

  • Strength training to maintain muscle mass

  • Flexibility work to preserve mobility

Even a short period of structured exercise before surgery, chemotherapy, or radiation can significantly improve a patient’s ability to tolerate aggressive treatments.

3. Exercise During Treatment

Exercise doesn’t stop being important once treatment begins. In fact, it can counteract many of the most challenging side effects of cancer therapy, including fatigue, muscle loss, and nausea.

Strength training, in particular, is a game-changer. One study by Dr. Courneya found that breast cancer patients who incorporated resistance training into their routine were 3.3% to 5.7% more likely to complete their chemotherapy cycles without needing dose reductions.

4. Exercise After Treatment

Even after treatment ends, exercise plays a critical role in recovery and long-term health. Cancer survivors who stay active are less likely to experience recurrence and have a lower risk of secondary diseases like hypertension, diabetes, and obesity.

How Exercise Fights Cancer at the Cellular Level

Exercise doesn’t just make you feel better—it actively changes your body’s internal environment in ways that make it less hospitable to cancer. Here’s how:

  • Improved blood flow to tumors: Exercise enhances circulation and oxygen delivery, allowing cancer treatments to reach tumors more efficiently.

  • Immune surveillance: Physical activity stimulates natural killer (NK) cells, which detect and destroy cancer cells.

  • Metabolic health: Exercise regulates insulin and glucose levels, reducing the availability of nutrients that fuel cancer growth.

Breaking the Myths About Cancer and Exercise

Despite the overwhelming evidence, many myths about exercise and cancer persist. Let’s set the record straight:

  • Myth: Cancer patients should rest and “take it easy.”
    Truth: Exercise helps patients maintain physical function and emotional well-being.

  • Myth: Strength training increases prostate cancer risk.
    Truth: Strength training is safe and beneficial for most cancer patients.

  • Myth: Exercise doesn’t matter if you’re already a healthy weight.
    Truth: Exercise improves metabolic health and reduces cancer risk, regardless of weight.

The Best Anti-Cancer Exercise

If you only have 15 minutes a day, Dr. Courneya recommends strength training with compound movements. These exercises work multiple muscle groups at once, maximizing efficiency and benefits.
