The importance of physical activity in cancer prevention, independent of diet and obesity, is becoming better understood. Twenty five percent of all adults engage in no leisure time physical activity. Less than half engage in moderate or vigorous physical activity.
By age 18 to 22 years, only 26 percent of males and 12 percent of females engage in moderate or strenuous activity at least five times per week.
Inactivity during childhood and adolescence is of particular concern because it increases the likelihood of being inactive as an adult, and less active adults are at greater risk of developing colon cancer, heart disease, and high blood pressure.
Cancers with an established or suspected association with physical inactivity include:
- colon
- rectum
- endometrium
- breast
- kidney
- ovary
- prostate
- lung
- testis
