Physical Activity Reduces Risk for Tumor Recurrence

Posted by Heinz-Josef Lenz, MD on January 3rd, 2010

You may know this already, but we have now more proof that physically activity reduces significantly your risk of tumor recurrence.

The study conducted by Dr. Jeffrey Meyerhardt from the Dana Farber Cancer Institute began in January 1986, included 668 men who’d been treated for stage I, stage II or stage III colon cancer that had not spread (nonmetastatic cancer).

Every two years, the men were sent questionnaires that asked them about any new cancer and disease diagnoses, as well as their physical activity. A metabolic equivalent task (MET) score was matched to each type of physical activity, with exercises that burned more energy receiving higher MET scores.

During the study period, which ended in January 2006, 258 of the participants died, including 88 who died from colon cancer. The results show that men who were physically active after diagnosis of nonmetastatic colorectal cancer experienced a significantly decreased risk of colorectal cancer-specific death, as well as death from any cause. This benefit was independent of age, disease stage, body mass index and tumor location and from the pre-diagnosis physical activity.

This manuscript was published in the Archives of Internal Medicine on December 14. These data show that physical activity will help in your fight against colon cancer for anyone.

Turn off your TV and start exercising.

    Dear Dr. Lenz,

    This is a little off topic, but you are the ONLY one that I trust. Your opinion is priceless to me.

    What do you think of an all raw food diet?

    I am an insulin dependant diabetic, and my husband thinks that if i went on an all raw food diet my need for insulin would just “dissapear”.

    He also thinks that a raw food diet will kill any cancer cell………..

    Thank you in advance.

    IF this would be true we would have no problems with diabetes and cancer. The juicing diets have been around for a long time in the treatment of cancer but have not shown to be of benefit.

    For the diabetes diet is important as you know but if you are insulin dependent (young and not insulin resistant) diet cant get you off insulin. If you are overweight and have insulin resistance you can sigificantly decrease your need for insulin or possibly get off it. Therefore it depends what kind of diabetes you have.

    In fact, you need to be careful of raw vegetables and fruit because sometimes your blood count drops and you are at higher risk for infections so raw foods should be avoided. Please discuss with your oncologists.

    Also raw foods can make you much more bloated or give you diarrhea. if you are have already these symptoms keep intake of them modest. Hope this helps
