Brisk walking may reduce risk of breast cancer - study

This is to report a study that suggests that brisk walking each day may cut the risk of breast cancer in postmenopausal women. We publish it here in the National Breast cancer Awareness Month or the pink month to remind readers that in many cases, breast cancer is preventable.

One study published in a recent issue of Archives of Internal Medicine suggests engaging moderate physical activity like brisk walking may moderately help reduce breast cancer risk in postmenopausal women.

The study shows postmenopausal women who engaged in physical activity equivalent to walking for more than one hour per day were 15 percent less likely to develop breast cancer, compared with those who did physical activity equivalent to walking for less than 1 hour per day.

For the study, Heather Eliassen Sc.D. at Brigham and Women's Hospital and Harvard Medical School and colleagues followed participants in the prospective Nurses' Health Study for 20 years during which 4,782 invasive breast cancer cases were identified.

The researchers found brisk walking was also associated with 10 percent reduced risk.

Other studies have already found physical activity may not only reduce the risk of developing breast cancer, but also risk of dying from the disease.

Many lifestyle parameters can be modified to reduce risk of breast cancer, which is diagnosed in more than 175,000 women and kills about 50,000 each year in the United States.

More reports will be published here in the National Breast Cancer Awareness Month to help readers to better understand the risk of breast cancer and how to reduce the risk.
