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, and family history of the disease.
Fortunately, there are ways to reduce some of these risks.
A study published by the Journal of the National Cancer Institute
examined the effects of physical activity and low BMI (body
mass index ‹ a measure of weight in proportion to 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;
lower BMI was also associated with an increased risk compared
with high 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; what's important
is that you participate in some form of exercise regularly.
