Researchers claim women who take regular brisk walks have a lower risk of developing breast cancer after menopause. Walking as exercise has been shown to reduce the risk of heart disease, cancer, type-2 diabetes, high blood pressure, anxiety, depression, and obesity.
Writing in the Archives of Internal Medicine, researchers collected data on 100,000 postmenopausal women, finding that women who did one hour of brisk walking each day were 15% less likely to develop breast cancer, compared to women who walked less than one our per week.
But reduced risk of breast cancer was not only seen among walkers. Women who got little exercise, but still increased their physical activity were 10% less likely to develop cancer than women who stayed inactive.
However, the researchers admit the study does not say walking caused less breast cancer, but the findings do highlight the importance of exercising for cancer prevention, especially after menopause.
In addition to exercise, diet is also an effective means of preventing cancer, specifically eating more fruits and vegetables, and less saturated fat. Antioxidants found in plants are known cancer-fighters.
Breast cancer is the most common cancer for women worldwide, killing an estimated 519,000 women in 2004, according to the World Health Organization.
