Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for
● Colon Cancer.
● Lung Cancer.
● Breast Cancer.
● Prostate Cancer.
In the Aerobics Center Longitudinal Study, more than 32,000 people （25,000+ men and 7,000+ women） were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level.
Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show lower rates of cancer with higher levels of physical fitness.
Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity（长寿） in a large group of men, some of whom were quite large. While results showed that fit and normal-weight is the ideal combination, researchers found that men who were fat but performed well on the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby（肌肉松弛）, men.
These statistics called for a warning for the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.
