Fast walkers Taxable Lower Risk of Breast Cancer

Women who walked briskly to regularly have a lower risk of breast cancer after menopause - and it's never too late to start.

From that research shows that highly active women are less likely to develop breast cancer than their counterparts who did not move much, but little is known about the impact of light exercise and whether women are less active who started doing sports will also get the same results .

The study, published medical journal "Archives of Internal Medicine", physician investigators A. Heather Eliassen, and a group of researchers from Harvard University reviewed the data about nearly 100,000 women who have menopause and examined them for 20 years.

There are many risk factors (conditions that increase the likelihood of disease) of breast cancer that women can not be controlled like a family health history or age when they start menstruating, it is clear Eliassen told Reuters Health.

But physical activity "is only one risk factor for breast cancer that women can follow up, and never too late to do so."

During the study, women reported how active they are and what type of exercise they do.

They are scheduled at least one hour per day to run faster or similar activities, 15 percent less likely to develop breast cancer than those who walked less than one hour per week.

Brisk walking means walking three to four miles per hour with a speed that makes it difficult to make conversation than during a leisurely stroll.

Even those who do little exercise before menopause but after vigorous activity, 10 percent less likely to develop breast cancer than those who remained inactive.

Overall, five of the 100 women developed breast cancer within 20 years.

Brisk walking seems to be the most protective action against breast cancer, more than swimming, hiking (hiking) or a leisurely stroll (jogging). But Eliassen stated that walking also became the most common form of exercise, which can reduce the validity of research results.

Regular exercise has been associated with a lower risk even after eliminating the potential effects of the alcohol drinking behavior and promote weight loss.

Forms of research can not provide evidence that exercise can lead to breast cancer a little more because because there may be other factors common to women in the study that also prevents breast cancer.

But it is merely "suggestions", although not yet clear why such an impact sport, says Eliassen.

Although previous research has shown that exercise reduces estrogen levels in the blood, these studies also have shown that exercise also reduces the risk of breast cancer because that is not influenced by estrogen.

"Physical activity also has an impact on chronic inflammation and insulin sensitivity. So there are several ways physical activity can be influential," he added.
