Mounting evidence continues to show that exercise may be a key component in successful cancer prevention and treatment. Studies have also found that it can help keep cancer from recurring, so it’s really a triple-win.

Yet not surprisingly few oncologists ever tell their patients to engage in exercise beyond their simple daily, normal activities, and many cancer patients are reluctant to exercise, or even discuss it with their oncologist. Hopefully, you will not be one of them.

Most recently, research announced at the 2013 International Liver Congress1found that mice who exercised on a motorized treadmill for an hour each day, five days a week for 32 weeks, experienced fewer incidents of liver cancer than sedentary mice.

Exercise may also be absolutely crucial in the treatment of depression, according to recent research.2 I’ve often stated this, and the science continues to support this advice.

Meanwhile, mounting evidence condemns the “evidence-based” drug paradigm, as reviews keep finding that large amounts of published drug research is either seriously flawed or outright fraudulent — motivated of course by the financial interests of the funding party.

Might Exercise Be a Key to Cancer Cure?

Hepatocellular carcinoma (HCC) is a cancer that originates in your liver cells, and is one of the most common types of cancers. According to the featured article inMedical News Today,3 HCC accounts for just over five percent of all cancers worldwide, and causes an estimated 695,000 deaths annually.

According to the reported research,4 the first of its kind for this type of tumor, regular exercise may be the key to significantly reducing your chances for developing liver cancer.

The study involved two groups of mice: One group was fed a high fat diet, and then divided into two sub-groups — one that exercised and one that did not. The second group was fed a controlled diet, and also divided into sub-groups of exercise and non-exercise. According to the featured article:

“After 32 weeks of regular exercise, 71 percent of mice on the controlled diet developed tumors larger than 10mm versus 100 percent in the sedentary group. The mean number and volume of HCC tumors per liver was also reduced in the exercise group compared to the sedentary group.”

In the high-fat diet group, exercise decreased the development of non-alcoholic fatty liver disease. Professor Jean-Francois Dufour told Medical News Today:

“We know that modern, unhealthy lifestyles predispose people to non-alcoholic fatty liver disease which may lead to liver cancer; however it’s been previously unknown whether regular exercise reduces the risk of developing HCC. This research is significant because it opens the door for further studies to prove that regular exercise can reduce the chance of people developing HCC.

The results could eventually lead to some very tangible benefits for people staring down the barrel of liver cancer and I look forward to seeing human studies in this important area in the future. The prognosis for liver cancer patients is often bleak as only a proportion of patients are suitable for potentially curative treatments so any kind of positive news in this arena is warmly welcomed.”

Exercise Needs to be Part of the New Standard of Care for Cancer

But the benefits of exercise are not limited to prevention alone. It can also help you recuperate faster and help prevent recurrence of cancer. A report issued by the British organization Macmillan Cancer Support5 just last year argues that exercise really should be part of standard cancer care. It recommends that all patients getting cancer treatment should be told to engage in moderate-intensity exercise for two and a half hours every week, stating that the advice to rest and take it easy after treatment is an outdated view.

According to Ciaran Devane, chief executive of Macmillan Cancer Support:7

“Cancer patients would be shocked if they knew just how much of a benefit physical activity could have on their recovery and long term health, in some cases reducing their chances of having to go through the grueling ordeal of treatment all over again…”

Indeed, the reduction in risk for recurrence is quite impressive. For example, previous research has shown that breast and colon cancer patients who exercise regularly have half the recurrence rate than non-exercisers.8 Macmillan Cancer Support also notes that exercise can help you to mitigate some of the common side effects of conventional cancer treatment, including:

Reduce fatigue and improve your energy levels Manage stress, anxiety, low mood or depression Improve bone health
Improve heart health (some chemotherapy drugs and radiotherapy can cause heart problems later in life) Build muscle strength, relieve pain and improve range of movement Maintain a healthy weight
Sleep better Improve your appetite Prevent constipation

Exercise Can Also Benefit Your Mental Health — Even When Forced

Many recent studies have shown that exercise provides a level of protection against stress-related disorders and depression. But could it still work if it was prescribed and forced upon you, by doctor’s orders, for example; or if part of a mandatory program, such as high school students or military, who are required to participate whether they like it or not?

To find out, researchers at the University of Colorado Boulder devised an animal study to determine whether rats that were forced to exercise would experience the same stress- and anxiety-reduction as those who were free to choose if and when to exercise.

The rats exercised either voluntarily or forcibly for six weeks, after which they were exposed to a stressor. The following day, their anxiety levels were tested by measuring how long they froze when placed in an environment they’d been conditioned to fear. The longer the rats remained frozen, like “a deer in headlights,” the greater the residual anxiety from the previous day’s stressor. According to the lead author:9

“Regardless of whether the rats chose to run or were forced to run they were protected against stress and anxiety. The sedentary rats froze for longer periods of time than any of the active rats. The implications are that humans who perceive exercise as being forced — perhaps including those who feel like they have to exercise for health reasons — are maybe still going to get the benefits in terms of reducing anxiety and depression.”

Could 89 Percent of ‘Landmark’ Cancer Research Be Untruthful?

Findings such as the ones above, which demonstrate the significant benefits of lifestyle changes like exercise on your physical and mental health, become all the more important in light of mounting evidence showing that conventional drug treatment research has been sorely compromised by industry funding. As discussed in a recent GreenMedInfo article,10 the alleged “groundbreaking” results of nearly nine out of 10 cancer studies cannot be reproduced by any means!

“This means that to an extent, we have based our healthcare and clinical guidelines on fake studies that reported untruthful results in order to accommodate the interests of industrial corporations,” Eleni Roumeliotou writes.

“Cancer is a major killer in US. The American Cancer Society reports that in 2012, more than half a million Americans died from cancer, while more than 1.6 million new cases were diagnosed. Given the seriousness of these statistics and the necessity of evidence-based medicine, it would make sense to trust that honest, objective research is tirelessly trying to find the best cancer therapies out there.”

Alas, this trust in the scientific rigor of medical research appears to have been misplaced. First of all, nearly three-quarters of all retracted drug studies are due to falsification of data,11 meaning it’s not even a matter of misinterpretation of data; rather the data used to draw conclusions are pure fiction. Large numbers of patients can be affected when false findings are published, as the average lag time between publication of the study and the issuing of a retraction is 39 months. And that’s if it’s ever caught at all.

Last year, former drug company researcher Glenn Begley also showed that the vast majority of the “landmark” studies on cancer are unreliable — and a high proportion of those unreliable studies come from respectable university labs. Begley looked at 53 papers in the world’s top journals, and found that he and a team of scientists could NOT replicate 47 of the 53 published studies — all of which were considered important and valuable for the future of cancer treatments!

Part of the problem, they said, is that scientists often ignore negative findings in their results that might raise a warning. Instead, they opt for cherry-picking conclusions in an effort to put their research in a favorable light. The allegations appeared in the March 28 issue of the prestigious journal Nature.12

“It was shocking,” Begley said.13 “These are the studies the pharmaceutical industry relies on to identify new targets for drug development. But if you’re going to place a $1 million or $2 million or $5 million bet on an observation, you need to be sure it’s true. As we tried to reproduce these papers we became convinced you can’t take anything at face value.”

As if that’s not disturbing enough, Roumeliotou points out that Begley was not permitted to disclose which 53 cancer studies he evaluated and found to be without scientific merit. She writes:14

“…when they contacted the original authors and asked for details of the experiments, they had to sign an agreement that they would not disclose their findings or sources. This shows that the scientists, who published the tainted research, were all along, fully aware of the discrepancies of their articles and criminally conscious of the fact that they were misleading the medical and public opinion.”

Your Lifestyle has Tremendous Influence Over Your Health and Cancer Risk…

In light of the evidence supporting the notion that lifestyle changes, such as exercise, have a profound impact on human health and diseases of both mind and body, it would be foolish in the extreme to ignore such advice. Especially when you consider that the conventional drug paradigm is riddled with unreliable and outright fraudulent research — courtesy of the financial influence of the drug industry itself, which funds the vast majority of drug research.

Studies on exercise and other lifestyle changes however are less likely to be fraudulent simply because there’s no money to be made by coming to the conclusion that exercise may be helpful — unless it was funded by a gym franchise, perhaps…

Whether you’re trying to address your mental or physical health, I would strongly recommend you read up on my Peak Fitness program, which includes high-intensity exercises that can reduce your exercise time while actually increasing your benefits.

Now, if you have cancer or any other chronic disease, you will of course need to tailor your exercise routine to your individual circumstances, taking into account your fitness level and current health. Often, you will be able to take part in a regular exercise program — one that involves a variety of exercises like strength training, core-building, stretching, aerobic and anaerobic — with very little changes necessary. However, at times you may find you need to exercise at a lower intensity, or for shorter durations.

Always listen to your body and if you feel you need a break, take time to rest. But even exercising for just a few minutes a day is better than not exercising at all, and you’ll likely find that your stamina increases and you’re able to complete more challenging workouts with each passing day. In the event you are suffering from a very weakened immune system, you may want to exercise at home instead of visiting a public gym. But remember that exercise will ultimately help to boost your immune system, so it’s very important to continue with your program, even if you suffer from chronic illness or cancer.

Role of exercise in cancer patients.

Mounting evidence shows that exercise can not only help cancer patients get well but also help keep their cancer from recurring. Yet, few oncologists tell their patients to engage in exercise beyond their simple daily, normal activities.

And many cancer patients are reluctant to exercise, or even discuss it with their oncologist.

A recent study1 by the Mayo Clinic investigated exercise habits among cancer patients and their clinicians’ roles in providing related counseling, and found that:

“Participants overwhelmingly cited usual daily activities as their source of ‘exercise.’ Symptoms, particularly treatment-related, discouraged participation, with fear of harm being a significant concern only among younger women. Exercise was recognized as important for physical and mental well-being, but seldom as a means to mitigate symptoms.

…Although respondents preferred to receive guidance from their oncologist, none reported receiving more than general encouragement to ‘stay active.’ A lack of direction was typically accepted as a sanction of their current activity levels. Participants appeared less receptive to guidance from ancillary health professionals.”

An Important Conversation You’d Be Wise to Have With Your Oncologist

Fear that exercise might be harmful appears to be largely unfounded, though it’s certainly understandable. It can be difficult to be enthusiastic about exercise if you struggle with nausea, fatigue, and other detrimental side effects from the treatment. However, it may be helpful to focus on the benefits you can reap from exercise. For example, research has shown that exercising during and after cancer treatment can:

  • Reduce your risk of dying from cancer
  • Reduce your risk of cancer recurrence
  • Boost energy and minimize the side effects of conventional cancer treatment (see additional listing below)

The fact that most oncologists overlook this vital aspect of their patients’ care is highly unfortunate, especially considering how most patients defer to their recommendations. However, it’s not unexpected. Conventional doctors are trained to prescribe drugs, not exercise.

Ideally, they’d prescribe exercise in the same manner drugs are prescribed – in specific “doses” and intervals. To do this properly, oncologists would be wise to develop relationships with personal trainers, and prescribe training sessions for their patients. If you have cancer, I would highly recommend discussing exercise with your oncologist, and/or work with a trained fitness professional who can help you devise a safe and effective regimen.

Exercise Needs to Be Part of Standard Cancer Care

A recent report issued by the British organization Macmillan Cancer Support2 argues that exercise really should be part of standard cancer care. It recommends that all patients getting cancer treatment should be told to engage in moderate-intensity exercise for two and a half hours every week, stating that the advice to rest and take it easy after treatment is an outdated view.

According to Ciaran Devane, chief executive of Macmillan Cancer Support:4

“Cancer patients would be shocked if they knew just how much of a benefit physical activity could have on their recovery and long term health, in some cases reducing their chances of having to go through the grueling ordeal of treatment all over again…”

Indeed, the reduction in risk for recurrence is quite impressive. Previous research has shown that breast and colon cancer patients who exercise regularly have half the recurrence rate than non-exercisers.5 Macmillan Cancer Support also notes that exercise can help you to mitigate some of the common side effects of conventional cancer treatment, including:

Reduce fatigue and improve your energy levels Manage stress, anxiety, low mood or depression Improve bone health
Improve heart health (some chemotherapy drugs and radiotherapy can cause heart problems later in life) Build muscle strength, relieve pain and improve range of movement Maintain a healthy weight
Sleep better Improve your appetite Prevent constipation

How Exercise Can Improve Cancer Outcome

This topic is near and dear to my heart, as I went to medical school in large part because I wanted to use exercise as a therapeutic tool to help people get healthier. I strongly believe that without fitness, it is virtually impossible to achieve optimal health. Lack of exercise can also severely hamper your recuperative efforts once disease has set in.

A 2005 study6 by researchers at Harvard Medical School found that breast cancer patients who exercise moderately for three to five hours a week cut their odds of dying from cancer by about half, compared to sedentary patients. In fact, any amount of weekly exercise increased a patient’s odds of surviving breast cancer. This benefit remained constant regardless of whether women were diagnosed early on or after their cancer had spread.

Similarly, researchers investigating the impact of physical activity on cancer recurrence and survival in patients with stage III colon cancer found those who were more active cut their risk of recurrence in half.7

One of the primary reasons exercise works to lower your cancer risk is because it drives your insulin levels down, and controlling your insulin levels is one of the most powerful ways to reduce your cancer risks. It’s also been suggested that apoptosis (programmed cell death) is triggered by exercise, causing cancer cells to die. This theory was demonstrated in two studies published in 2006. In one, mice who used running wheels developed fewer and smaller skin tumors.8 The second study found that exercise reduced the number and size of intestinal polyps.9

The studies also found that the number of tumors decreased along with body fat, which may be an additional factor. This is because exercise helps lower your estrogen levels, which explains why exercise appears to be particularly potent against breast cancer.

If you’re male, be aware that athletes have lower levels of circulating testosterone than non-athletes, and similar to the association between estrogen levels and breast cancer in women, testosterone is known to influence the development of prostate cancer in men. Strength training may be of particular benefit. In one 2009 study10, men who regularly worked out with weights and had the highest muscle strength were between 30 percent and 40 percent less likely to lose their life to a deadly tumor.

Other research has shown:

  • Exercising moderately for six hours a week may reduce colorectal cancer mortality11
  • Three hours per week of moderate-intensity physical activity may lower risk of prostate cancer mortality by about 30 percent12, and lower the rate of disease progression by 57 percent13

Of course, exercise also improves the circulation of immune cells in your blood, whose job it is to neutralize pathogens throughout your body. The better these cells circulate, the more efficient your immune system is at locating and defending against viruses and diseases, including cancer, trying to attack your body.

Exercise Tips for Cancer Patients

I would strongly recommend you read up on my Peak Fitness program, which includes high-intensity exercises that can reduce your exercise time while actually improving your benefits.

Now, if you have cancer or any other chronic disease, you will of course need to tailor your exercise routine to your individual circumstances, taking into account your fitness level and current health. Often, you will be able to take part in a regular exercise program – one that involves a variety of exercises like strength training, core-building, stretching, aerobic and anaerobic – with very little changes necessary. However, at times you may find you need to exercise at a lower intensity, or for shorter durations.

But remember that exercise will ultimately help to boost your immune system, so it’s very important to continue with your program, even if you suffer from chronic illness or cancer.

Intense Workouts May Also Be Safe for Heart Patients

Another group of people often discouraged from exercise are those suffering with heart problems, but even here the mindset is starting to change. In an about-face in the way patients recovering from heart attacks or heart surgery are typically treated, a new study14 suggests high-intensity workouts may in fact be a safe choice. The study followed 4,800 Norwegian heart patients who did aerobics. Only three cardiac arrests occurred in over 170,000 hours of intensive exercise in these patients.

According to Reuters:15

“The number was too small to say for sure that high impact workouts are just as safe as moderate ones, but they show the overall risk of exercise bringing on cardiac arrest is fairly low, according to the authors. There is plenty of evidence that the harder people work out, the more benefit they gain in cardiovascular function, said Oeivind Rognmo, a researcher at the Norwegian University of Science and Technology in Trondheim and lead author of the study…”

The participants completed both moderate- and high-intensity workouts, spending a combined total of 129,456 hours working out at moderate intensity and 46,364 hours at high intensity. Moderate intensity workouts included an hour of walking, or other exercises resulting in exertion at 60-70 percent of maximum heart rate. The high-intensity workouts consisted of four-minute-intervals (cycling, running, or cross country skiing), pushing their heart rate up to 85-95 percent of maximum, followed by four-minute-long rest periods.

During the more than 129,000 combined hours of moderate exercise, one person died from cardiac arrest. And during over 46,000 combined hours of high-intensity workouts, two suffered cardiac arrest during or within an hour of exercise, but both survived. According to the lead author:16

“We found that both types of intensities were associated with low event rates… I think (high-intensity training) should be considered for patients with coronary heart disease.”

Remember to Listen to Your Body

One of the key principles I teach and believe in is to listen to your body. This applies no matter what your current state of health is. If your body will not allow you to exercise, either due to pain or worsening of your underlying condition, then you have no practical option but to honor your body’s signals and exercise less.

Even though your body desperately needs the exercise to improve, you will only get worse if you violate your current limitations. So you may have to start with as little as just minutes a day. That’s okay. As your body gradually improves so will your tolerance to exercise, and you’d be wise to do as much as your body will allow in order to achieve a high level of health.

Additional Strategies to Help Prevent Cancer

While exercise is an important facet of cancer prevention and treatment, it’s certainly not the only one. I believe the vast majority of all cancers could be prevented by strictly applying the healthy lifestyle recommendations below:

  • Avoid sugar, especially fructose. All forms of sugar are detrimental to health in general and promote cancer. Fructose, however, is clearly one of the most harmful and should be avoided as much as possible.
  • Optimize your vitamin D. Vitamin D influences virtually every cell in your body and is one of nature’s most potent cancer fighters. Vitamin D is actually able to enter cancer cells and trigger apoptosis (cell death). If you have cancer, your vitamin D level should be between 70 and 100 ng/ml. Vitamin D works synergistically with every cancer treatment I’m aware of, with no adverse effects. I suggest you try watching my one-hour free lecture on vitamin D to learn more.
  • Avoid charring your meats. Charcoal or flame broiled meat is linked with increased breast cancer risk. Acrylamide – a carcinogen created when starchy foods are baked, roasted or fried – has been found to increase cancer risk as well.
  • Avoid unfermented soy products. Unfermented soy is high in plant estrogens, or phytoestrogens, also known as isoflavones. In some studies, soy appears to work in concert with human estrogen to increase breast cell proliferation, which increases the chances for mutations and cancerous cells.
  • Improve your insulin receptor sensitivity. The best way to do this is by avoiding sugar and grains and making sure you are exercising, especially with Peak Fitness.
  • Maintain a healthy body weight. This will come naturally when you begin eating right for your nutritional type and exercising. It’s important to lose excess body fat because fat produces estrogen.
  • Drink a quart of organic green vegetable juice daily. Please review my juicing instructions for more detailed information.
  • Get plenty of high quality animal-based omega-3 fats, such as krill oil. Omega-3 deficiency is a common underlying factor for cancer.
  • Curcumin. This is the active ingredient in turmeric and in high concentrations can be very useful adjunct in the treatment of cancer. For example, it has demonstrated major therapeutic potential in preventing breast cancer metastasis.17 It’s important to know that curcumin is generally not absorbed that well, so I’ve provided several absorption tips here.
  • Avoid drinking alcohol, or at least limit your alcoholic drinks to one per day.
  • Avoid electromagnetic fields as much as possible. Even electric blankets can increase your cancer risk.
  • Avoid synthetic hormone replacement therapy, especially if you have risk factors for breast cancer. Breast cancer is an estrogen-related cancer, and according to a study published in the Journal of the National Cancer Institute, breast cancer rates for women dropped in tandem with decreased use of hormone replacement therapy. (There are similar risks for younger women who use oral contraceptives. Birth control pills, which are also comprised of synthetic hormones, have been linked to cervical and breast cancers.)

If you are experiencing excessive menopausal symptoms, you may want to consider bioidentical hormone replacement therapy instead, which uses hormones that are molecularly identical to the ones your body produces and do not wreak havoc on your system. This is a much safer alternative.

  • Avoid BPA, phthalates and other xenoestrogens. These are estrogen-like compounds that have been linked to increased breast cancer risk
  • Make sure you’re not iodine deficient, as there’s compelling evidence linking iodine deficiency with certain forms of cancer. Dr. David Brownstein18, author of the book Iodine: Why You Need It, Why You Can’t Live Without It, is a proponent of iodine for breast cancer. It actually has potent anticancer properties and has been shown to cause cell death in breast and thyroid cancer cells.

The organization offers loads of helpful information about the benefits of exercise for cancer patients on their website, and also has a number of videos on the subject, available on their YouTube channel.
