Walking is a great way to get healthy and stay healthy, and it may reduce a woman’s risk of breast cancer or its recurrence. Walking can also help control your weight, which has been linked to breast cancer.
Researchers from Washington University and Harvard University evaluated nearly 65,000 women who filled out questionnaires on their level of physical activity at various periods of their lives, starting from age 12. Women whose activity was equivalent to 3.25 hours a week of running or 13 hours a week of walking had a 23 percent reduced risk of breast cancer compared with those who had been less active.
“It did not seem to matter much what the activity was; the differences between strenuous, moderate, and walking activities were not statistically significant. You don’t have to be a marathon runner to get the risk-reducing effects of exercise,” commented Dr. Graham Colditz of Harvard.
In another study, breast cancer survivors who exercised at least three to five hours a week reduced their risk of recurrence or death from breast cancer by 40 percent compared to those who were inactive.
Weight also has been found to be a risk factor. Women who gain between 21 to 30 pounds after 18 have a 40 percent increase in risk of breast cancer even if she wasn’t a perfect weight when she was younger, an American Cancer Society study found. The reason is tied to the rise of overall body fat which results in increased insulin and estrogen levels, both of which have been linked to breast cancer.
