Breast cancer survival improves if women stay active

Breast cancer survival improves if women stay active: "People who walk and get other kinds of exercise are less likely to develop many common health problems, including heart disease, high blood pressure, osteoporosis and diabetes. Several studies also suggest exercise can prevent breast and colon cancer, and it may also help stop endometrial, kidney and esophageal cancer.

Generally, doctors recommend at least 45 minutes of moderate to vigorous exercise five times a week. This might prevent colon cancer by speeding the movement of food through the intestines. Exercise might also reduce breast cancer by burning up stored fat that produces estrogen, which in turn can fuel breast cancer growth."
