Regular Exercise Significantly Cuts Colon Cancer Risk


A new study confirms that regular exercise significantly decreases colon cancer risk.



As I discuss in my book, A Cancer Prevention Guide for the Human Race, as many as 60 percent of new cancer cases are directly linked to modifiable lifestyle and dietary factors, including many of the worst cancer killers.  Cancers of the gastrointestinal tract, including colon and rectal cancer, have been particularly linked to lifestyle and dietary factors, as I extensively discuss in my book.

A newly published study in the Journal of the National Cancer Institute is an exhaustive meta-analysis study of 21 previously published clinical trials that, in turn, evaluated the link between physical activity levels and colon cancer risk.  As an aside, meta-analysis is commonly used to combine the data from multiple similar clinical research studies, and then analyze that data in such a way that the “statistical power” of the combined meta-analysis study is usually greater than the individual studies that are being evaluated.

When the data from these 21 previously published clinical studies was combined and analyzed, the authors of this new meta-analysis study found that people who regularly engaged in high levels of physical activity were 27 percent less likely to develop cancer in the upper part of the colon when compared to people who were not physically active.  Similarly, highly active people were found to have a 26 percent decrease in the risk of developing cancer in the lower colon when compared to sedentary people.

The link between high levels of physical activity and decreased colorectal cancer risk noted in this meta-analysis is consistent with the research data that I discuss in A Cancer Prevention Guide for the Human Race (as well as other lifestyle and dietary risk factors that are associated with colorectal cancer risk).  A Cancer Prevention Guide for the Human Race is now available in both printed and digital formats from all major bookstores.  Get your copy now, and begin living an evidence-based cancer prevention lifestyle!

At this time, more than 8 percent of Americans are unemployed.  According to the Bureau of Labor Statistics, however, the unemployment rate for veterans who served on active duty between September 2001 and December 2011 is now more than 12 percent.  A new website, Veterans in Healthcare, seeks to connect veterans with potential employers.  If you are a veteran who works in the healthcare field, or if you are an employer who is looking for physicians, advanced practice professionals, nurses, corpsmen/medics, or other healthcare professionals, then please take a look at Veterans in Healthcare. As a retired veteran of the U.S. Army, I would also like to personally urge you to hire a veteran whenever possible.
