Avoid Colon Cancer with EXERCISE

The American Cancer Society estimates that nearly 95,000 new cases of colon
cancer will be diagnosed in the United States this year. The exact cause of colon
cancer is unknown, but some of the risk factors are known: a high-fat diet,
inadequate fiber intake, or family history of the disease.

Fortunately, there are ways to lower the risk of colon cancer. A study
published by the Journal of the National Cancer Institute examined the effect
of physical activity and low BMI (body mass index -- a measure of your weight
in proportion to your height) on the risk of colon cancer. 

The study included 63 men and women with a history of polyps in the colon
(another risk factor for the development of colon cancer). Researchers found
that subjects who participated in consistent leisure-time physical activity had a
reduced risk of colon cancer compared to more inactive subjects; higher BMI
was also associated with an increased risk compared with low BMI.

Leisure-time physical activities include walking, jogging, aerobics, and
moderate housework or yardwork. Working out in a gym isn't the only way to
exercise, but what's important is that you do some form of exercise regularly. If
you'd like more information on staying healthy, or would like advice on an
exercise routine that's right for you, consult your doctor of chiropractic.
