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 in Medical 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 control 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 allpatients 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.
